Solutions

1. Set jakarta.persistence.validation.mode to one of the recognized values: auto, callback, or none (case-insensitive).
2. Fix typos in the mode value in persistence.xml or the configuration map.
3. Remove the property entirely to fall back to the default AUTO behavior.

When it happens

Trigger: The jakarta.persistence.validation.mode setting contains an invalid or mixed value.

Common situations: Typos in the validation mode (e.g. 'calback'), or listing incompatible modes such as NONE together with CALLBACK/AUTO in a comma-separated list.
