Hi John,
Apologies for the delay. I looked at this case, and your query returns the following error when run against my account:
Failure: { "errors": [ { "errorCode": { "queryError": "EXPECTED_REFERENCED_FIELD_IN_SELECT_CLAUSE" }, "message": "The following field must be present in SELECT clause: 'segments.conversion_action_name'." } ] }
If you add segments.conversion_action_name as a field in your query, it should work for you.
Cheers
Anash
