Hi because it's a dictionary then you would have to get the value with a key.

We know response is a dictionary, so in this case when you want the value from the documentation_url, we would need to do it like this:

    def get_github_json(url):
        response = requests.get(url).json()
        return response

    assert get_github_json(url)['documentation_url'] # <---- your are getting the value by giving the key

If you try and print out response['documentation_url'] then you would get this result: https://developer.github.com/v3/activity/events/#list-public-events

Looks like you are not returning a instance of HttpResponse from your view. could you paste a code snippet? also, please try to unfold a highlighted exception (it's coloured with a dark grey background) and see what's the value of 'response' variable.

It looks like you need to set the load_instance Meta class attribute to True, according to marshmallow-sqlalchemy docs. As suggested by G. Anderson, you can try to print the update object's type for confirmation, but it seems you are getting a default dict as the deserialized data, instead of an instance of your Application model, which could be achieved by doing the above-mentioned trick. The code could be written like this:

class ApplicationSchema(SQLAlchemyAutoSchema):
    class Meta:
        model = Application
        include_relationships = True
        load_instance = True
