ONLINE_MODE, OPS and WHITELIST don't have effect

[x1unix]

Describe the problem

I have a docker-compose file with whitelist and ops values.
The second other-user is not known nickname, so I disabled online mode.

Problems:

• I get complains about other-user nickname although online mode is disabled
  • Invalid parameter provided for 'manage-users' command: Could not resolve user from Playerdb: other-user
• I can't join game even if I'm in WHITELIST. I'm using Prism Launcher with Microsoft Account logged in.
• OPS var doesn't work. I'm a regular user even when that value is defined.
  I had to grant myself admin privileges via console as OPS didn't have effect.

Your logs don't match your compose file since it's looking for https://playerdb.co/api/player/minecraft/peregonb

and not "other-user"

Visiting the URL confirms the reported error

{"message":"No Minecraft user could be found.","code":"minecraft.invalid_username","data":{},"success":false,"error":false}

[x1unix]

@itzg I tried to redact my friend's username but forgot one place :)

Looks like the issue is that mc-image-helper still performs validation even if offline mode is disabled.

[itzg]

I don't understand. Offline mode or not you're trying to put a username into ops/whitleist. It has to call the 3rd party API to resolve the username. How is the system supposed to convert a name to a UUID otherwise?

[x1unix]

@itzg is it possible to skip username to UUID conversion step?
To just use username instead of UUID.

[itzg]

Yes, you can provide UUIDs instead of username
