[Fabric] Permissions data for user was not loaded during the pre-login stage
See original GitHub issueDescription
When you try to join a Fabric server through BungeeCord/Waterfall using FabricProxy, LuckPerms does not allow that login because player’s data couldn’t be loaded during the pre-login stage.

Reproduction steps
- Create a Fabric and a BungeeCord/Velocity server
- Put FabricProxy (only on Fabric server) and LuckPerms as mods
- Try to log in to the server and you’ll see the error in the console.
Expected behaviour
A successful login was expected.
Environment details
- Server type/version:
Fabricrunning version1.16.5loader0.11.1and usingFabric API 0.30.0 - FabricProxy version:
v1.4.6 - LuckPerms version:
v5.2.99
Any other relevant details
I have also tested this using online-mode and Velocity and the same error occurs. I also saw similar closed issues but didn’t help. I’m using everything up to date.
Also tested with FabricProxy-Lite (1.0.1)

This issue has been solved with the last version of FabricProxy-Lite (https://github.com/OKTW-Network/FabricProxy-Lite/issues/1). I leave the link here if somebody needs info about this.
As you can see from the log, the pre-login event is being called with the UUID
859a0db5-6499-3552-96ea-c8543a67ff75(looks like the offline mode UUID) and the login event with31c7be0d-89fc-401e-9d16-bafca8739984(looks like an online mode one!).Both UUIDs should be the online one - this is most likely an issue with the mod which is providing Velocity support.
