Solutions

1. The embedded result mapping references a non-embedded attribute. Map only embedded attributes with embedded result mappings.

When it happens

Trigger: A JPA result mapping for an embedded/identifier attribute is invalid: Embedded result mapping specified non-embedded attribute: <value>

Common situations: @SqlResultSetMapping/@MappingElement definitions referencing non-embedded attributes, missing column names, or duplicate member mappings.
