i run into this because i want to dump the response object into a yaml file.

products_api = mws.Products()
products = products_api.get_x()
mydict = vars(products)  # same as products.__dict__
type(mydict['_response_dict'])

this returns
luigipipe.mws.mws.utils.ObjectDict

i think it should return: dict

A very simple approach for problems of that kind i found here.

If you think that is a good idea i can try to understand and fix this.
