Upload endpoint not working because of JSON serialization.

[Purrloin4]

When trying the Upload function with a file as the payload it gives an error because of not JSON serializable. Executed code:

with open('TiestoF.pdf', 'rb') as f:
    payload = {'file': f}
    bbObject.Upload(payload = payload)

Error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
