Issue with ArcGIS Server Feature Service and AttributeError in Python

Introduction: I am encountering an issue with an Esri ArcGIS Server Feature Service link. Over the past few days, the link has been functioning correctly; however, starting yesterday, it started throwing an error. As a newcomer to FME, I lack the necessary understanding to interpret the error message, specifically the AttributeError: 'NoneType' object has no attribute 'name'. I would greatly appreciate any assistance in resolving this issue.Problem Description: The link causing the problem is as follows:Link: https://mapservices.weather.noaa.gov/tropical/rest/services/tropical/NHC_tropical_weather_summary/MapServer/Details: Upon accessing the aforementioned ArcGIS Server Feature Service link, I receive the following error message in Python:Python Exception <AttributeError>: 'NoneType' object has no attribute 'name'Request for Assistance: Since I am new to FME, I am unsure about the root cause and implications of this error.

How come JSON null values are handled differently by different transformers?

Hi folks, While working with some JSON data, I seem to have noticed that null values are sometimes interpreted as a literal string, instead of a true <null> value (like non-existent/empty). When I just tried to replicate this, it seems that different FME JSON transformers seem to handle null values in a different manner. E.g. when using a JSONFragmenter or a JSONFlattener, it seems that null values are indeed recognized as true <null> values (like non-existent/empty), but when using a JSONExtractor or an XMLXQueryExtractor (with a JSONiq query), it seems that null values are returned as a literal string. Of course in the latter case I could add a NullAttributeMapper transformer to change the literal string 'null' to the <null> value, but this seems like a bit of a workaround (and also, how would you then distinguish between a literal string value "null" in JSON, and the true null value) Is there something I'm missing, or is this a bit of a bug? K

PDF2TextReader does not recognize my published parameter for selecting a pdf file into the transformer. Anyone else experienced this?

PDF2TextReader does not recognize my published parameter for selecting a pdf file into the transformer. Is there any workaround this? PDF2TextReader runs when I select the pdf file directly but not when I use a parameter in selecting it.

Documentation for Deployment Parameters?

It looks like Deployment Parameters might make some of our processes more manageable. Is it intended for use with workspace runners? Is there any documentation out yet for this new feature?

FME through Windows Task Scheduler

I have a workspace which is scheduled through Windows Task Scheduler on a Virtual Machine. This workspace writes out to an Excel file on a mounted drive. When running the workspace manually, it has no issues. However when running through Task Scheduler, the workbench gives an error "Can't open file for writing". The target Excel is not opened anywhere and I do have writing permissions for it. Has anyone dealt with a similar issue before?

how to select rows based on start and end values from previous rows

I have a table of values with ID, Start, and End. Starting with the first row, I need to select the next row where the start value equals the end value of the first row. I need to repeat this process for the entire table. For example, I'd select row 1 then row 4 then row 6 then row 9 then row 13...Any thoughts on how to do this?

"Job Status: Awaiting Worker" - job is endlessly stuck - Thoughts on cause?

For a job that has been working for years, it is now endlessly polling job status and returning awaiting worker. In Server, the last message you get is about the Socrata Write executing. In the desktop software you get more information and it reflects endless polling. Something has changed and I'm having trouble figuring out the cause. 2 of 24 of these (county specific) ran and the rest hung, and now even the two that ran initially will hang. It appears to be happening in the last step involving the Socrata Writer. This is the last log information, with the "Polling the job status: Awaiting worker" repeating endlessly. Other jobs that write to Socrata are still working. It isn't blanket failure on writing to Socrata. Any thoughts on cause or leads to investigate are welcome. ThanksSocrata Writer: 0 features treated as points, 0 features coerced to point, 0 features with unsupported geometries written without geometrySocrata Writer: Invoking Socrata DataSync with control file action 'Ap

Read a single file from a zip file

I have a zip file that has a csv file and multiple jpgs. I tried a CSV feature reader-- not a CSV reader-- as I was trying to read the file with in the zip file but that didn't work. I am using FME 2022.2.2. Is there a way to only extract a particular file from the zipfile? I dont want to unzip the entire thing as it will take a long time. Thanks in advanced.

How to read INSPIRE ATOM GML?

I have this GML dataset (https://service.pdok.nl/hwh/administratieve-eenheden/waterschapsgrenzen/atom/downloads/administrativeunit.gml). I tried all kinds of configurations with the different GML readers (although I expect the INSPIRE GML reader to be ready for it). I can't get it to work. I also don't have much knowledge of the ATOM standard. Any directions for help?

Oracle Spatial reader very slow

Hello,I am experiencing difficulties reading an Oracle Spatial table with FME.The table (linestring) has about 250K records.FME starts to log the first 10000 records after about 10 minutes. And then 10000 at a time every 6 minutes.The table is displayed in GeoMedia and also QGis in about 5 minutes.Feature Caching is disabled.I have tried both with the reader and with a SqlCreator. Same results.What checks/configurations can I try?This is the first time it happens and not sure if some metadata could be wrong or corrupted.This sounds strange because of the tests with other products.TIARoberto

Waiting for FME Server jobs to complete

I have an intermittent problem where an FMEServerJobWaiter fails to wait for a job to complete and rejects it after 30 mins-or-so when in fact the job is still running and completes successfully (it gets rejected with a 502 gateway error).Is there a difference in the way the FMEServerJobWaiter works compared to the Wait for Jobs to Complete parameter in the FMEServerJobSubmitter? - might that give more reliable performance?Using FME2021.2.

Switch Esri Geodatabase Reader/Writer from traditional Versioning to Branch Versioning

Is it possible to switch the Versioning in an Enterprise Geodatabase (on SQL Server) from "traditional" to "Branch Versioning" without touching FME Workspaces containing Esri Geodatase Readers and Writers (GEODATABASE_SDE)? In a first attempt in the test environment, everything seems to be running like before, after we switched to Branch Versioning of our feature classes. A quick look in the geodatabase tables seems to prove that the internal fields like GDB_ARCHIVE_OID, GDB_FROM_DATE, ... are filled correctly. Can it really be that simple? Does FME support the switch to Branch Versioning while keeping the Workspaces untouched? Of course, this would be a dream, but this seems too good to be true.

How do I spatially select polygons that have a set of points that fall within them, merge the attributes of the point and polygon datasets and then write out only the polygon features?

I have a large polygonal dataset and a point dataset with 178 records. I need to select the polygons that have a point within them, merge the attributes of the two and then write out a polygonal feature class to later be consumed in GIS project inside Arc Pro. I have tried Point On Area Overlay but the output Point data does not contain any attributes from the Polygonal dataset and vice versa. I have also tried Spatial Relator / Spatial Filter with no luck. Any suggestions greatly appreciated!

What are best practices for handling special characters that cause HTTPCaller to fail?

We are using HTTPCaller to batch geocode thousands of records, but we are running into an issue with special characters that are causing the HTTPCaller transformer to fail. As a workaround, we've been using multiple (20+ at this point) String Replacement transformers to catch and modify the special characters before going to HTTPCaller. Geocoding the same input table using the Geocode Table wizard in ArcGIS Pro completes without issue. Are there certain characters that HTTPCaller cannot handle, or is there a better or more robust workaround than using String Replacements? Can anyone offer insight into why the input table geocodes successfully in ArcGIS Pro without any data sanitization/cleansing in ArcGIS Pro, but fails in HTTPCaller? Thanks in advance for any help you can over. @natalie_campos @acueva

How do I compare the total record count of the same 4 feature classes in 2 file geodatabases and then send a notification email if the counts are exactly the same?

I'm currently using a file gdb reader, a statistics calculator to get the total counts, attribute manager to create fields called Today_Count and Yesterday_Count and then the conditional value in attribute manager to try and compare the two counts and return a 1 if they're exactly the same but I can't seem to get the comparison to happen. Also how do I set this up so that if the counts are exactly same I can send out an email notification?
