Exception Value: Incorrect padding This happened first when I was developing on my Android device using Termux app. I switched my browser to Google-Chrome and the issue was resolved. Then today I was developing on my PC, using qutebrowser and this error popped up again. Switching to Google-Chrome fixed the issue. I don't think this is an issue with the browsers themselves, because I have completed entire django projects in both these devices, and never had to switch to Chrome. The only differences happen to be- This is my first time using djangorestframework, first time using django 3.1 Is this a bug that has leaked into django 3.1 inadvertently? -- You received this message because you are subscribed to the Google Groups "Django users" group.
