CanPlaceOn and CanBreak don't work
Summary
I have been testing around with CanBreak and CanPlaceOn in the files, but every time I try it out it gives me the error that the item is not properly configurated and it returned to null. I have used the examples from the wiki and tried out many options, but it either doesn't work at all or just completely breaks. Please note I am using MythicMobs on Aternos!
Steps to reproduce
Really it's just create any item with the CanBreak and/or the CanPlaceOn prompts.
Current behavior
An error pops up saying 'Could not get item: item is improperly configurated and returned to null.'
Intended correct behavior
If I use "/mm i get " that has the prompts in its code, it should give me the item like with any other and have the working attributes.

I'm a little lost here... Sorry :/
Proposed fixes
It should simply give me the item without errors and work like intended... right?
