    314         raise JSONDecodeError("Unexpected UTF-8 BOM (decode using utf-8-sig)",

TypeError: the JSON object must be str, not 'bytes'

What should I do ?

Can you convert the data type of response to string

Which version of python are you using?

[Krasaa]

I have same problem, how do you solve it? @dibgerge I 'm using python3 in win10 with jupyter notebook.

[Krasaa]

I find that despite the problem, the grades are updated as usual so maybe the bug can be ignored.

[chrisadas]

I confirm the same errors with Python 3 on Ubuntu. And that grades are registered despite the error message.

See pull request #11 suggesting a fix.

See pull request #11 suggesting a fix.

That fixed it for me.
