I do not have any error but for reference, here we go!

Bug Description

Literally the MC-276292 bug, but only on backwards versions. On the native server versions, its working nicely.

Steps to Reproduce

• Have a 1.21.3 PaperMC server with ViaVersion and ViaBackwards latest.
• Connect in 1.21.1.
• Get in creative.
• Try to clear your inventory with shift-clicking the "Destroy Item" slot in the creative inventory.
• and tada! the inventory is cleared in server-side. Client-side, you still have your inventory.

Expected Behavior

It should clears inventory.

Additional Server Info

I use latest versions of every plugins I have.

My build was from Spigot and tried out your snapshot ViaVer build, same bug. Also, an additionnal error shows.

Please update all Via* plugins from https://ci.viaversion.com/.In case the issue still persists send the new dump and the issue will be reopened

[FlorianMichael]

Don't insult our bot, he is correct. Please update to dev builds from https://ci.viaversion.com/

[alzhetv]

Please read. I tried. Same error, same shit.

[FlorianMichael]

Send a new dump url then

[alzhetv]

Its updated 💀

[FlorianMichael]

You need to update ViaBackwards as well

[alzhetv]

there is no build at https://ci.viaversion.com/

[FlorianMichael]

https://ci.viaversion.com/view/ViaBackwards/job/ViaBackwards/

[alzhetv]

Still the same bug. https://dump.viaversion.com/84c30283a5ccd23ef313abb03eedf01812e2cb2d0564d7f4a62fa3e696235b54

And they should add ViaBackwards and ViaRewind on the homepage by the way of the jenkins website lol. It could save some time.

[FlorianMichael]

There are, you just have to read.

I can't reproduce the exception issue when using the latest ci from both ViaVersion and ViaBackwards, so you either just uploaded a new dump without doing testing again or something else in your setup is wrong.

Then i am sorry, it was not really easy to read, i meant viabackwards and viarewind writed like ViaVer Dev/Java8. As I don't use this Jenkins tool too often and as there is no dark theme, my eyes get flashed everytime i access that site. I dont add dyslexia to it but you get it.

Do I still require to do this ? Cuz the same problems occurs on the same dump version.

I saw an update and gonna try back again.

Inventory handling is a bit annoying to read through and handle, but I think all that it needs in ViaBackwards is sending empty inventory contents when detecting that action

[alzhetv]

As far as I know, when i do my inventory cleaning by destroy item, i know that Crazy Auctions plugin syncs the inventory on /ah. Thats a workaround for me until the issue will be resolved in a near future, i hope. <3

[alzhetv]

Still the same on latest versions. https://dump.viaversion.com/3bc07a28774b8cb50670cc93c36f7b698b92448b5a139e41ffa94c61720b87f6
