Since upgrading from FME Flow 2025.2 to 2026.2, we are seeing a recurring authentication problem with our Workspace Apps. When a user opens or reloads an app, a native browser Basic Authentication popup appears intermittently, roughly every second or third load. Because we use SAML, our users have no local username or password to enter and are forced to click Cancel every time. After cancelling, the app works normally, but the repeated prompt is disruptive for end users.Our setup: FME Flow runs under HTTP behind an IIS reverse proxy (Application Request Routing) that enforces HTTPS. Authentication is handled through SAML with Azure AD as the identity provider using SP initiated login. On IIS, only Anonymous Authentication is enabled while Windows and Basic Authentication are disabled, and the SAML base URL is correctly configured.Using the browser developer tools, I captured the exact request that returns the 401. It is a GET to the Data Upload Service that the app fires in the backgro

In FME 2026.x, the way Double data types are identified seems to have changed. Decimal numbers are only recognized as double when using a period ('.') as the separator, whereas a comma (',') is not. This is quite unusual, unlike previous versions which worked perfectly fine with commas.I believe the identification method in previous versions was more efficient. For large workspaces, it could save us from using additional Transformers to convert commas to periods. Moreover, since input data formats in different regions still use commas as decimal separators, keeping the old identification logic would be much more flexible.  

I have successfully created a Asana app for connecting to FME (giving me a Client ID and secret) and then established the connection as a web connection in FME Form, but when I try to use the AsanaTaskQuerier transformer and input the required parameters (Web Connection, Asana Project ID, and Query Type) the Asana Project ID gives me an error, “Arithmetic expression invalid”. I followed the help documentation for the custom transformer and it seems straight forward enough, but no matter which Project ID link I copy and paste into the field, it gives the same error and won't let me click OK to run the transformer. I have successfully tested the connection and know that works, the issue seems to be in the Asana Project ID, possibly because it seems to have to be an Arithmetic field? The FME Help documentation for this says to input the Asana Project ID as follows, which I have done so in the same format. Does anyone have a solution to what the issue is or if you have come across this iss

We are working through the setup of a service user for a project, intended to only be able to create and run its own Data Virtualization APIs and nothing else.  The aim is to avoid excessive permissions. I have been searching for a list of recommended or minimum permissions but have not yet established that, so I’m putting the question out here.We have granted:Create/manage for data virtualization Run jobs Access Resources/DataWe’re looking into other permissions.We’ll work through it but I am definitely thinking that documentation of this would be handy from the Safe point of view to save time, if possible.  Possibly as an addition to https://support.safe.com/hc/en-us/articles/36098228739469-Secure-Data-Virtualization-Endpoints-with-Authentication 

Quick question; if I want to use a token to authenticate my Data Virtualization, rather than a FME Flow user, I need to build it myself, correct? (and then do that for all endpoints of course)

Hi there,I am importing connections from an older deployment of FME Flow into Form, in order to publish to a new FME Flow. When I do so their names are locked to whatever they were named before.  These names do not confirm to our new naming convention.  It would be helpful to be able to rename Web and DB connections in Form. I understand this would possibly break workspaces referencing this, but this is a risk I am willing to take.

How can I check the extension on input files for FME appsFor example a file with a DWG extension Thank you for answer

I'd like to read a DGN file, which contains a terrain model. In version 2025.1.2 it is being read as igds_polygon_collection. The fme_Geometry is “fme_undifined” and the fme_type is “fme_no_geom”.When using a Civil 3D file, it can read a surface model, which is the same principle as the terrain model in a DGN. The terrain model is created in OpenRoads.Or is another option available to read the terrain model directly from a DGN file without converting it to another fileformat or element type?  

Hi everyone!Today I’d like to share a new approach to building reports in FME, along with an entire family of custom transformers I’ve created to support it. Why I built BRGI’m a long-time fan of the HTMLReportGenerator. It lets me craft reports quickly, and I love the versatility of HTML compared with, say, PDF. I even demo it in every Intro to FME course as a great example of “let FME handle the code.”But as much as I love it, I’ve always hit three pain points:1. Plain styling – it could really use a dash of CSS/Bootstrap.2. Hard-coded content types – adding a new chart or HTML element isn’t trivial.3. Cumbersome feature ordering – managing Sorters and AttributeCreators just to control layout can get messy.Earlier this year I had to build a highly procedural report with lots of HTMLLayouters, AttributeCreators, and Sorters, and the workspace quickly turned into spaghetti. That’s when I thought: I already improved SystemCaller with BetterSystemCaller… why not do the same for report ge

Hi everyone,After upgrading our FME Flow instance from 2025.2 to 2026.2, a workspace parameter with dynamic values stopped working in a Workspace App.When opening the app, FME Flow shows the following error when testing the dynamic parameters:Loading from WorkspaceKartenautomatisierungen/Kartenautomatisierung_ZUBA_PreScript_2.fmwError loading schemaUnable to generate dynamic parameters from source file.Error was:E:\appdata\fme\systemshare\resources\system\null\null\FeatureWriter\ZUBA.jsonPlease ensure the file exists and is readable. A few observations:The same setup worked without issues in FME Flow 2025.2. The workspace itself executes successfully. It loads the JSON after the workspace is done.  The error only occurs while loading the dynamic workspace parameter. The path contains system\null\null\FeatureWriter\ZUBA.json, and the corresponding folders do not exist. I never configured FME to write schema files to that location.Has anyone seen a similar issue after upgrading to 2026.2

We're using the TrimbleUnityConnector in FME Workbench 2026.2 and have noticed that when creating a new activity, the connector displays template options for items such as inspections. However, no Work Order Template options are available.As a workaround, we've been passing the Work Order Template ID as an attribute, which works, but we'd expected the templates to be selectable in the connector like the other activity types.Has anyone else experienced this behavior, or is there additional configuration required to expose the Work Order Template options?Here is inspections for comparison
