The database is not compatible.

You can try migration instructions from here:

https://www.h2database.com/html/migration-to-v2.html

Thank you,

However i am no db expert. i have no idea how to upgrade the database now. is it a simple command or is it hard to do?

Here is the same problem after updating the Docker container. The h2 database does not start and throws the same error.

Any tips on how to solve this?

You need to migrate the database. See the link.

Hello Anton,
unfortunately, I feel the same way as Chris. I do not understand the instructions in the link. Can you maybe give us tips how to update to the new h2 version.

Thanks a lot

Hello,

These instructions mean nothing to me either. I didn't know what to do with it. Thank you it went very well. According to them, this cannot be based on this either.
