Backup & Restore nbt bug

[yPedroDev]

Hello, would there be a way to fix this? When I enter the server, all my items and those of the players are simply reset. I end up getting this message when I try to restore:

[02:31:58 INFO]: yPedroDev issued server command: /bp restore yPedroDev_dab21994ec104c31ae4672124dd07a43_1718759564925 [02:31:58 ERROR]: [Minepacks] Failed to deserialize NBTItemStack

the same error happens when the player enters the server, my server has a lot of people, and I have to resolve this orgently.

[GeorgH93]

Update to 2.4.31.1, then only the problematic item should be missing, and its JSON should be printed in the log.

[yPedroDev]

The error starts to appear when I start using version 2.4.31.1

[yPedroDev]

I can't use older versions, I've already tried but the plugin gives another error and ends up being disabled

[GeorgH93]

Can you send me that backup file?

[JustSimplyGaming]

I have the same issue. Luckly only 4 of over 50 people joined since the automatic Update. I set my server under maintenance, so no backpack can be override. I tried to install an older Version of the last days, but still have the same error: [Minepacks] Failed to deserialize NBTItemStack No backup matching Cily30_dca098c7c98d4c0cbdfd3bdbb35385cf_1718785862724

But the file is in the Backup folder

Can you please send me that file.

Also, what is the output of /version.

[JustSimplyGaming]

Cily30_dca098c7c98d4c0cbdfd3bdbb35385cf_1718785862724.zip Current Purpur Version: 1.20.6-2227-79d199c (MC: 1.20.6)*

• You are 6 version(s) behind Download the new version at: https://purpurmc.org/downloads Previous: 1.20.6-2226-86ad0b3 (MC: 1.20.6)

Pluign Version is now 2.4.31.2

[JustSimplyGaming]

But this happens with every Backupfile.

[GeorgH93]

Could you give this build a try. With it, I was able to restore your backup file.

[JustSimplyGaming]

On the frist look, it looks good. Players that didnt joined before the Update, have the backpacks as saved.

[GeorgH93]

Sounds good. For the ones that have joined since the update, you should be able to restore their backpack with the /backpack restre command

[JustSimplyGaming]

I have multiple feedbacks now. Everything works fine now. Thanks for the Update :) BTW. this version works on 1.21 to :D

[yPedroDev]

Invalid tag id: 31 <= Is this any indication of the problem?

[GeorgH93]

There is no tag id 31 The new version was just not handling compressed backpacks correctly. But that should be fixed with 2.4.31.3

[yPedroDev]

Ok, there's just one problem, when players who had items enter the server, they will lose their items, yesterday I recovered my items manually, today I updated to the version you showed to update, when I went to test with my secondary account and my original , the items ended up being reset, but now the backup system works normally and the error also stopped happening, but I don't have a backup for all the players, just some, would it be possible to load the items without this having to happen? I looked in the database, and saw that the old players' items are still there, but when they enter the server they end up being reset.

[GeorgH93]

I would expect v2.4.31.3 to load everything correctly, if that is not the case, please send me the backup file that was created for that case.

[yPedroDev]

did you mean the .backpack files? or backpack.db?

[yPedroDev]

If you meant the .backpack files then, I will only be able to give one file because the others ended up being deleted because I thought they were corrupt, when I tried to restore the backups it said No "backup name here" matching.

[GeorgH93]

Yes, please give me the backpack file. If you still have an issue opening old backpacks in 2.4.31.3, there should be newly created ones anyway.

[yPedroDev]

archive-2024-06-19T120515-0300.tar.gz

[GeorgH93]

Loads fine for me. Can you please double-check that you are actually on v2.4.31.3 (/bp version)

[yPedroDev]

Ok, I realized that it seems to fix it, when I have problems I open another github issue. Thank you for your help

[yPedroDev]

I tried it with another player and it loaded without any problems.
