OPS or WHITELIST doesn't work in offline mode

[klucsik]

Im working with java version
I installed the server with the helm chart, added player usernames to the ops and whitelist fields, like this:
whitelist: User1,User2,User3,User4,klucsik
ops: User1,User2,User3,User4,klucsik
overrideServerProperties: true

The server is freshly installed, its in offline mode, but I got rejected with the klucsik username.

Is it possible to use whitelist/ops in offline mode?

I looked into the volume, and the uuid-s are different than the ones in the usercache.json. If I populate the whitelist/ops from the usercache, it works.
