There's no such thing as UUID4 in the Python uuid module -- there's
UUID (which is the class representing UUIDs), and there's the function
uuid4 (note that it's lowercase, it takes no arguments, and it will
return an instance of UUID).

The two UUIDs in that JSON snippet look correct at a first (and
second) glance. Have you tried using a debugger, or just a
quick-and-dirty print statement to see what value is being passed into
uuid.UUID that makes it raise an exception?
My guess would be that the JSON file contains a value somewhere that
is not a correct UUID, but I may be wrong, of course.
