FME Flow

Hello Safers, I am currently planning on implementing a FME Flow server that I’ll need to use within an ArcGIS Enterprise that is federated. I understand based on the documentation that I need ArcGIS Server installed and licensed on that server before attempting to install FME Flow. This have I have already done. I’m now onto creating a site for this machine. I imagine this site would be federated with my ArcGIS Enterprise? We also have a separate server that contains all of our Web Adaptors. Would install the Web Adaptor the same as any other ArcGIS Server, and separately have the Apache application server install on my FME Flow? I would then use the aforementioned to create a reverse proxy so that external traffic is then routed onto our FME Flow server. Does this not effectively mean there are two different configurations: One to direct traffic to our ArcGIS Server site, and then another to our FME Flow Web Application Server? Basically, the question above is: I would configure my A

I wanted to share a project I’ve been working on : a way to "watch" a PostgreSQL table using FME Flow Automation. Since I began working with FME Server/Flow, Automation has always stood out as one of its most powerful and easy-to-demonstrate features. The ability to trigger workspaces based on incoming emails or new files and automatically send notifications, consistently makes an impact during demos. But one question kept coming back:“Can I detect changes in a database table and trigger workspaces from that?” For a long time, my answer was: “Not really”, or at least, not in a clean or recommended way. I used to think the best option was for the database to notify FME Flow, not the other way around. For instance, in PostgreSQL, you could use a trigger on insert/update/delete and call an FME Flow webhook using something like the PL/Python or pgsql-http. That method is covered here:- 🔗 4 methods for tracking data changes in FME (blog post) - ▶️ Triggering FME with your Database (YouTube

Hi, I’m trying to downoad FME Flow 2024.2.5 package for Linux Debian 11, but the link is broken: https://downloads.safe.com/fme/2024/deb_11/fme-flow-2024.2.5-b24832-linux-x64~debian.11.run Maybe a Safer can check this issue. Thanks!

The FME Server docs do a good job of telling you how to uninstall and reinstall Server, whatever configuration you choose. However, if you want to migrate from last year's FME Server to the latest release, you have to backup and uninstall everything first. This might work fine for an Express install. But if you have a distributed install of FME Server, the server backup only contains the workspaces, repositories, services and supporting files from your last install. Your previous architecture's configuration isn't stored anywhere. How would you recommend backing up your previous distributed configuration settings (network locations, ports, service account names, etc) to make it easier to install the new release so you have the same configuration as before?

So in one of the tutorial for creating AR, the screenshot of FME Flow has the Create AR App option in Flow Apps. But I opened my FME Flow 2025.02 version, it only appears these options without Create AR App: Is anyone having the same issue? Is there anything I did wrong? Thank you so much for the help.

Hi, I’m running into an issue with FME Workbench 2021. When I run the workspace locally, all expected files are generated correctly. The same workspace also works when published to our older FME Server (same version, 2021.0). However, after publishing it to a new FME Server environment (also 2021.0), some of the output files are missing. No errors are reported in the log, but certain files simply don't get written. The log even says they have created the files. Nothing has changed in terms of file paths or logic – they still use dynamic paths (e.g., FME_SHAREDRESOURCE_TEMP). The only major change is that we replaced FeatureReader with HTTPCaller to avoid a bug with esri_OID in high availability setups. I’m running the exakt same job but still I get this issue. I’ve already: Verified that the paths are correct Checked resource locations Tried republishing and updating the “download data” edit. Still, the problem remains in the new server setup. What could be causing this?

I followed the advices in the troubleshooting from ​@lizsanderson21 to setup a custom Python interpreter in FME Flow under Windows. I did so because I needed to install pandas in a version that requires numpy to be more recent than the one that comes with FME. So far I thought all went fine, but when I call numpy.__version__ from within a PythonCreator then the version number returned is 1.26.2. When I use pip.exe list from within my custom Python installation folder then the numpy version returned is 2.2.6 → matching the version number from when I installed numpy through pip.I also installed pandas and SQLAlchemy through pip and the version numbers returned from the PythonCreator do match the version numbers pip.exe list returns. I wonder why numpy seems not to be used from the custom Python installation but rather from a fall back version that comes with FME Flow. Did I forget some step? I installed Python 3.12 on the FME Flow machine I ran the following three commands with the paths

Hi there, I have an FME Flow automation set up triggered by a survey123 submission. When i submit a survey from survey123 on my computer it works fine and runs the automation. When submitting from my mobile device however nothing comes through, the automation doesn’t run. Any help would be much appreciated, cheers.

Hello everyone, I have some experience with Workspace apps, but not as much with Automation apps. In my previous work with Workspace apps, I created an app that is based on user input on a map. When a user clicks on the Run button, the "Running..." button appears. Once the script finishes successfully, the user can download a ZIP file by clicking on the Datadownload URL. Now, I’m trying to build something similar using an Automation app, but I’ve found the process to be quite different. Based on the following post, I’ve set up the following: I have a manual trigger that includes a manual parameter called "Geometry" (GEOM). This GEOM parameter is then used in the subsequent Workspace. Similar to the Workspace app, I want to show a "Running..." button while the script is running, and once it finishes, makes a download URL available to the user. However, the only feedback to the user is the green "Automation Triggered." message. There’s no further feedback for the user, that the script is

Hi All, We have recently ran into an issue with using a SharePoint Multitenant web connection of FME Flow. A connection/client id/client secret has been created in azure and used to creat the mutlitenant connection within FME form and then published up to flow. This connection works the day of but when added to a schedule to run daily, it fails out the next time it runs. When we go back in and authorize the connection again in flow, it seems to work. Is there a particular setting in the connection or azure to keep this connection active? Thanks,

We have set up our remote engine on another server, now I’m trying to configure a remote engine in FME Server 2022, but the tab is not visible. How do I get it to show?

It is common knowledge that Flow has to be on the same server as ESRI ArcGIS Server for all the ESRI toys to function correctly.How does this work with a Remote Engine? If we have 2 servers, one with Flow and the other with ArcGIS Server, can we overcome the licencing issue by installing a remote engine on the ArcGIS Server machine? I see from this article Using FME Flow with Esri ArcGIS Software – FME Support Center that it states“ArcGIS Server must be installed and licensed on the same machine as the FME Flow Engine Service”, but what does this mean in practice…???? The “Flow Engine Service” means the main installation of Flow, rather than Remote Engine, yes? Any help will be warmly appreciated. Regards Stu

Hi All, Does anyone have any experience and examples for calling FME server from a QGIS processing script? I have published some (data download) workspaces in FME server into workspace apps for my end users within the company. They really like this, but they would prefer not to leave QGIS. I would like the script to place the zip file returned bij FME server in a folder and unpack it. Thank you.

Hello, I am a newbie and want to use fmedownload api in our new webpage. what is the best way to integrate security? at the moment I would call the the get token service with user and password to get a temporary token. Then I would use this token and call fmedownload. Is that the best way? Will the token service be available in the future? thanks best regards Gerhard

Hello, Does anyone know how to create triangles between two 3D lines using FME tools? The triangles can also be vertical.

I am creating a PDF report in a PythonCaller and currently I am writing it into a subfolder of FME_SHAREDRESOURCE_TEMP. I would like to know where I have to write the file to be able to generate a download link for it.When I use normal writers than I reference the writer in the Download Service… but with a PythonCaller?

Hi everyone. I need to display an outline of GIS data on a basemap that runs in a Flow app. For example, an area shapefile. This is to display the area of operations, as a starting point when using the app, and the users will then select areas within that area to grab other data (addresses and statistics etc). I’ve been working through this: Using the Geometry Parameter – FME Support Center to get a workspace built and published to Flow. But how do I ensure the outline of the area of operations is displayed from the very start? I am a bit of a noob when it comes to Flow apps, so please do not worry about over-explaining anything: I need all the help I can get! Many thanks in advance. Stu

Hi everyone, We are planning an fme upgrade shortly and I want to compile a list of the workspaces, automations and other items we have on our FME Flow instance to help plan for testing, and determining the amount of effort etc we will need to plan for. Is there a way of doing this? Does anyone have a process they can share? Have had a look at using the api interface and http callers and could set something up with this, but hoping someone might have already done this that I could adapt for my systems. Or that there is a simpler native way that i have missed. TIA Jacky

Hi, I get from our Security officer anmessage that there is an vulnerability dected on one of our servers.This server is has FME Flow 2023.2.2 Build 23781 - win64 which depend on Apache Tomcat.Can you tell me if there is an security risk? And how we can solve this? Thread is registered under: CVE-2023-44487. Thank you

I have several automated jobs that use either a startup or shutdown python script. These scripts run fine in workbench and even in the ESRI Python interpreter on the Flow machine. The issue arises when I run them from Flow. When it gets to the script it will output expected products until the exportToPDF command at which point it fails. No errors are indicated anywhere except in the Engine Log where this is displayed: WARN localhost_Engine2 393562 : Process "localhost_Engine2" ended unexpectedly. Being restarted on attempt 1… Example of script: import arcpy, os, sys, time, shutilfrom datetime import datetime sdpFolder = r"****OBSCURED****"exportFolder = os.path.join(sdpFolder, "SiteDevPlanFiles")date = time.strftime("%Y-%m-%d")dateFolder = os.path.join(exportFolder, date) archiveFolder = os.path.join(sdpFolder, "_Archive") zipExportFolder = exportFolder + ".zip" # from zipfile import ZipFile# for file in ZipFile(zipExportFolder).namelist(): # archive previous zip destZip = os.path.join

We have an automation that is triggered daily with a CRON expression which runs 4 workspaces. The first 3 workspaces are run in parallel and the fourth runs on successful completion of one of the workspaces. Last night, two events appear to have been triggered at the scheduled time and so each workspace was run twice. Has anyone ever come across anything similar? I can’t see any obvious errors in the logs

Want to create a Session Token with JavaScript and api. What is the way to do it with rest api v3? best regards Gerhard

I accidentally deleted the wrong automation in FME Flow and I am not able to see how I can recover it.
