Stack trace and error logs

Hi @maxdobler
Thank you for reporting this.

2.2.0 is mostly a maintenance release with a change to date time handling. However it is difficult to pinpoint the issue.

How is the datetime field configured? Does it have a schema annotation and is it of type OffsetDateTime?

Also, can you increase the loglevel (DEBUG or even TRACE) to check if there is an exception or something unexpected? https://www.springwolf.dev/docs/faq#show-debug-output-in-the-logs
