Create Merchant Stock - Not working (might be me though)

[mrbwhitby]

I cannot get the Macro 'Create Merchant Stock' working.

I get the error:

VM2229:105 Uncaught (in promise) TypeError: Cannot read property 'data' of undefined
at generateMagicItemsStock (eval at _executeScript (foundry.js:14665), :105:14)
at addToActor (eval at _executeScript (foundry.js:14665), :131:9)

I've tried multiple Compendiums and Actors. None generate any Inventory into any character.

Thanks in advance for any help
