FME Server 2022.2

Build 22765 - win64

I have an ArcGIS Portal Feature Service writer set up to update a single attribute. I am getting the following error ArcGIS Portal Feature Service Writer: Encountered an unexpected error. The error code from the server was '400' and the message was: 'Unable to complete operation.'. Details: 'True curve update not allowed.'

I have specified to not update the spatial column so I would expect this error would not occur.

imageIt would appear that FME is trying to send a geometry image

You can try to use the geometryremover transformer beforehand and set your writer geometry to arcgisonline_no_geom. It might also be possible that only the latter also works but just try out a combination of these two options.

 

Or you can change the settings on the ESRI service to allow updates from non curve clients.
