@reachvimalm , There is some problem with the data you are posting. The API is not able to interpret your data properly. Since you are using python requests module, I suggest using the json keyword when doing a requests.post()

I got such an error from GitHub API when I didn't send any POST data.

I was able to solve it. My request was not correct.

[hckr]

My request also wasn't correct, it lacked message body.
