Hello,
When "FeatureServer" service is coming from PostGIS database then certain queryTask is not working properly.
We get {"code":400,"message":"Unable to complete operation.","details":["Unable to perform query operation."]}}.
PostGIS 13.1
ArcGIS 10.8.1
Thanks!
What is the version of Postgres being used?
Can you run a select by ..... in ArcGIS Pro?
Does the data display in a map service?
