Solutions

1. The query's actual result type differs from the requested type. Pass the correct result class, or adjust the query's select list.

When it happens

Trigger: The requested result type does not match what the query produces: Incorrect query result type: query produces '<value>' but type '<value>' was given

Common situations: Creating a typed query whose result class differs from the query root/select item type, or passing a result type for a non-select statement.
