Error merging money

[eI1on]

Whenever I merge money in my inventory I get this error, but the money is merged with the correct modData and display name.

The issue seems to be here: https://github.com/Chuckleberry-Finn/pz-shops/blob/72762b4ac4d698589b00c2e05137af93f6da2247/Contents/mods/pz-shops/media/lua/client/shop-wallet.lua#L303

I will look into it, the behavior is successful/works as expected otherwise?
