exceptions occurred while processing the subscribers to the 'item:saved'

Question

Whenever I try and copy a single item anywhere, I get this error. I have serialized the item and it has a template.

NOTE: This is an item in a branch

Answer 1

I am going to file this under doh. I'll leave this question for anyone who sees this error.

This is because the template for the item does not exist in the local environment. That's embarrassing.
