We are using ArcGIS REST Services (Version- 10.71), for querying distinct values in the table, however, most of the time our query return error: “Error performing query operation” with a 500 error code.
In the table, there is a total of 330094 records, of which only 24420 should be returned with a given where clause (Play='Permian Delaware Tight, US').
Moreover, there are only 201 distinct values in the given field('operator') when aforementioned where clause is applied.
Mainly my query contains following constraints:
where = Play='Permian Delaware Tight, US'
outFields = 'operator'
returnGeometry = false
returnDistinctValues = true (optional, even if we set this to false, we're still getting the issue)
returnCountOnly = true

I believe this is a simple query and should not throw exceptions. Please let me know if I’m missing anything here.
Layer settings are as follows: (which I believe are correct for a given query to run)
Supports Advanced Queries: true
Advanced Query Capabilities:
Supports Statistics: true
Supports OrderBy: true
Supports Distinct: true
Supports Pagination: true
Supports TrueCurve: true
Supports Returning Query Extent: true

Thanks for any help in advance.
