Solutions

1. Verify the database's GUID generation function (e.g. newid(), uuid()) works in the configured dialect.
2. Check the JDBC connection and dialect settings for GUID support.

When it happens

Trigger: Thrown when the database did not return the expected generated key/identity value after an insert.

Common situations: Typical situations: JDBC driver not returning generated keys; use_get_generated_keys disabled with a dialect lacking identity selection; triggers interfering with key retrieval.
