TypeError: 'NoneType' object is not iterable

I just ran graffiti-monkey for the first time, and while all the volumes were tagged appropriately, graffiti-monkey crashed when it came to tagging snapshots with the same tags.

Here's the output from the error:

Could we see your command line and config yaml file?

[PaulCapestany]

@paulwakeford sure thing! I should probably have included them from the get-go, oops…

Command

▸ graffiti-monkey -c ~/.graffiti-monkey.yml
