Pex migration > User cannot be found
Closed this issue · 29 comments
Hello I have run into an issue after migrating from pex to luckperms.
Description:
After migrating from pex to luckperms, all luckperms commands do not work with usernames. It seems I have to use UUIDs only to edit or pull up info about a user. I know its better to use UUID anyways, but not all plugins have uuid placeholders (such as EZPrestige, or other ranking plugins). It is very strange, though, because the plugin seems like it has all the info it needs. If I run the command via UUID it even outputs the correct username.
NOTE: I, VoidAngel, have logged on to the server multiple times after migrating, so I should be in the luckperms cache, but it seems I am not somehow. See the below console output:
Evidence:
24.07 13:36:51 [Multicraft] VoidAngel ran command: lp user VoidAngel info
24.07 13:36:51 [Server] INFO [LP] A user for VoidAngel could not be found.

Is there a way to fix this? Perhaps a command? or something at startup to correct all the users?
Things that don't work:
- Restarting the server
- Being online while running the command
- Turning on "use-server-uuid-cache" DOES work in a sense, but the luckperms cache still does not update D: I'm worried about too many requests to Mojang by leaving it on. I have a lot of servers and a lot of players so I have to be careful about that. Correct me if I'm wrong please.
Ah right I should mention that. xD
I'm using the default h2.
Also I'm on Luckperms 4.2.17 and Paper Spigot 1.12.1
Hmm. Could you perhaps export your perms, delete the h2 and reimport please?
Ive migrated about 6 servers from pex to luckperms already. They all have the same issue, but its not always the same users that dont get migrated correctly. On a few servers I can run "lp user VoidAngel info" with no problem, but for a user that is online even at that moment I can type "/lp user exampleuser info" and it will tell me that the user cannot be found.
Given the fact that I have already done this many times I dont think the outcome will change xD
But if you have something else in mind that I am not thinking of, I will try exporting and migrating again.
Export, don't migrate
Literally type /lp export test /lp import test into console
But that does sound like a bug 🤔 cc @lucko
That worked :D The cache is now updating itself when players log in.
Thanks for the help codingJWilliams.
Can you see if the migration works on the latest version? The version you’re using is quite old...
I’d recommend using your old PEX data on a test server to see if it’s working.
Ah I see. I was just using the spigot release version when I made this ticket.
I just changed to v4.2.54 and tried migrating another server to pex and the same thing happened unfortunately. D:
using "/lp user VoidAngel info" while I was online returned no results.
Ive got my work around so I dont really care if its fixed xD I just want you guys to know that the bug still exists.
@BrainStone
Yes and yes
Doing the PEX migration shouldn't have any impact on how UUIDs are being saved by LP. Once a player has connected once, they should be permanently cached in the plugins storage.
Do you have any other plugins installed which could possibly be preventing LP from handling the connection, or clearing the data after they've logged in?
From what I’ve seen almost everyone that migrates has issues resolving player names. Exporting, wiping and importing usually solves the issue, as that completely wipes the username cache.
Just had another case today.
So the PEX migration must somehow mess up the player cache.
Which storage type @BrainStone ?
I'd like to try to reproduce this myself, have been unable to so far.
I can pass you a pex permissions.yml if you would like to test it with a large permissions file that can very likely reproduce the problem.
All I did to migrate was:
- Install luckperms with a brand new luckperms folder generated.
- While pex is still on the server, do /luckperms migration permissionsex
- Wait until the migration is done, then remove pex and restart
After this you should find that most users (not 100% of them though) will not be cached correctly.
You might need to insert a fake record or something to make it work for you though (?) Juts thought about that because you wont have any data in that pex file for your minecraft account 🤔 And making brand new records with luckperms by just logging in might not reproduce the issue.
Please can you confirm that this is fixed in .58.
The underlying bug has been fixed (so it won't happen on new migrations), and any data already migrated will be "fixed" when each player next connects to the server.
Hmm there's been another member with this issue, don't know what version they were running
The new version is working great for me as far as I can tell. However, I'm still observing to make sure everything is correct.
Marking as fixed for now.
@codingJWilliams Quite likely they were still using an older version.
