It looks like Panilla is not happy with an NBT tag in BagOfGold. Panilla provides the opportunity to accept specific NBT, but I don't know what it is. Is there a way to find out, or could you just post it. For references, the Panilla configuration entry is

# Whitelist NBT tags from being checked
# Keep in mind some NBT tags vary between Minecraft versions
#     (eg: ench on 1.12 vs Enchantments on 1.13)
nbt-whitelist:
#  - Enchantments

I dont know Panilla, but I guess it is Panilla that should change something? Isnt it?

I dont know what an NBT tag is?

Trying to get PowerNBT updated to MC 1.19.x, so I can capture the NBT. See https://github.com/SlimeDog/PowerNBT/issues/1
