title: Result: Failure Exception: TypeError: argument should be a bytes-like object or ASCII string, not 'dict'
body: <p>I'm having a problem with this homework where I'm sending a post request with an encoded image base64 as a json object in postman. I'm supposed to decode the json body and save it as an image on azure blob storage. I was successfully creating the blobs as txt but I haven't got much luck this time. Any help will be much appreciated</p>
