Could not pass event PlayerInteractEvent - related to inventory size???

[EchocallingEarth]

So, I'm testing for 1.21.4 and have encountered an error related to Lootin' and what I think is chest/barrel inventory size, but truth be told I have no clue. Anyways here is the error as it appears when clicking on a chest/barrel: Error encountered

Note clean world fresh install and setup running latest stable Paper build
when I came across a feature with a barrel in it, I clicked on the barrel and this error popped in console, but the chest did not open. No time-out or crash occurred.

Further searching to find a chest (double chest in this case) and error happened again.
Please note that some single chest did not throw the error which seems to be related to the inventory set in said chest/barrel

If you require additional information including plugin list or datapack list, please do not hesitate to ask.

Thanks

do you have a plugin/datapack that changes the inventory size of chests/barrels?

We use several datapacks, but I don't see any that would push the loot_table past the container max. Also, we have been using the same packs previously (Versions of MC before this alongside Lootin') and have encountered no issues. However, I can easily send you the folder with the datapacks in it, in case you see something we missed or something that changed.

Figure posting here was easier than discord especially when sharing stuff, at least in theory.
If you have additional questions or want me to try something like remove a specific pack, or try tweaking a pack just let me know, you can either reply here or ping me on discord and tell me to check the GitHub.
