Running ArcPro 2.8.1
I'm trying to run SQL queries on text field of a hosted feature layer but am given "There was an error in the expression." when making a definition query and "ERROR 000358: Invalid expression" when using the 'select by attributes' tool. Same result regardless of whether I'm using the query builder or writing the SQL query directly. I've tried simplifying to something as simple as "Field IS NOT NULL" to test but no luck.
What's really strange to me is that I can run queries on every other field in this feature layer.
Any ideas?
