I have a workspace in FME Workbench 2022.2 that reads an ESRI ArcGIS Server Feature Service containing 7 layers. It successfully reads all 7 layers and transforms them to the appropriate feature types.
That same workspace in FME Form 2023.1.1.1 is able to read in the number of features for all 7 layers but only able to successfully read in the features for 3 of the 7 layers. On the 4 layers that fail it appears to be failing after the first batch of 1000 records are requested. As a test I created a new project with only the FeatureServer reader in FME Form 2023.1.1.1, again same problem. As another test I tried using the MapServer endpoint for the service rather than the FeatureServer endpoint that failed on the 4 layers. This successfully read in all 7 layers.
ArcGIS Feature Service Reader: Got 4222 results for layer/table ID 0
ArcGIS Feature Service Reader: Splitting reading of 4222 features into 5 batches of up to 1000 features
ArcGIS Feature Service Reader: Getting feature results 0 up to 1000 of layer/table 'NetD Enclosures'
ArcGIS Feature Service Reader: Encountered an unexpected error. The error code from the server was '400' and the message was: 'Unable to complete operation.'. Details: ''
An error has occurred. Check the logfile above for details
Has anyone else seen this? Thanks.
