"message": "Failed to execute query.",
The server is running version 10.31. My query was built by example from the docs (https://developers.arcgis.com/rest/services-reference/query-map-service-layer-.htm) and I've tried PROJECTNUMBER with and without the quotes.
Am I missing something?
Hi Lars Fagerbakke,
I think your query should be
i.e. Field name unquoted and value single quoted
I tested this with this URL:
Does this solve your issue?
