Solutions

1. The method was called on a mutation native query but requires a SELECT query.
2. Use a SELECT native query, or use executeUpdate() for mutation queries.

When it happens

Trigger: A query object is used through an interface or role it does not implement.

Common situations: Casting or unwrapping a native/HQL, select/mutation query to the wrong type, or passing a non-property path where one is required.
