install djangorestframework-simplejwt==4.6.0 and see if this solves your problem

I'm using djangorestframework-simplejwt==4.6.0 and I had the same issue. Fixed by using pyjwt==2.0.0 instead of the newer version pyjwt==2.0.1

[dj-cao-dz]

I looked at the source code djangorestframework-simplejwt and pyjwt.The reason for this error is thebackends.TokenBackend.encode, which returns thetoken.decode ("utf-8"). in pyjwt 2.0 and later jwt.encode method returns str directly instead of the previous' bytes'. To avoid this error, we can use the version of pyjwt less than 2.0, or wait for simplejwt to be modified.

Sorry about this. In the middle of finals (and in the middle of midnight). I'm going to see if I can get permission from @auvipy or @jezdez to push out a release which includes #349 that should fix it.

[Andrew-Chen-Wang]

Please give me ETA May 3rd ish to get SimpleJWT 4.7.0 out.

[Andrew-Chen-Wang]

Scratch that. @auvipy I'm not "project lead" but I've had SimpleJWT 4.7.0 laid out for about a month or two; you think it's good to go? If so, just create the release from the GitHub UI (there's a GitHub action that should automate it hopefully)

[Andrew-Chen-Wang]

Sorry for the long wait y'all. v4.7.0 is now released.

[grvrai]

Please update this on pip too

[Andrew-Chen-Wang]

@grvrai it's on pip. We only allow Python 3.7+
