Negative index in crash report handler (0/21) / Error executing task on Server

[zedwick]

Describe the bug
Inspecting a chest with item transaction history yields an error in the logs.
The inspect otherwise appears successful, and shows the history in chat.

To Reproduce
Steps to reproduce the behavior:

1. Place a chest
2. Place any item into chest
3. /lg inspect
4. Left click on chest

Expected behavior
Everything seems to work, but I do not expect the error in the logs

Device Info(please complete the following information):

• OS: Debian
• Minecraft Version: 1.17
• Version: 1.0.1

Additional context
The error does not show when left clicking an empty chest with no other history besides placing the chest.

I disabled networking (networking = false) in the config, assuming it might be related to that, and restarted the server. I now see a slightly different/expanded error in the log when inspecting a chest with transaction history:

That’s the same error- and the networking code doesn’t fire on any in game action, unless a packet is sent to the server with the ledger ID

[zedwick]

Aye, it's just got a little more on the bottom and is missing the Negative index in crash report handler (0/21) line before it.

It may have just been the restart which changed the logged error slighty.

[Genau6502]

Would have been the same log anyway - the top one is a cut off one. Potato’s fixed it now

[PotatoPresident]

You can grab the fixed version from github actions

[zedwick]

Confirmed as fixed. Thank you.
