[SOLVED] Django GraphQL JWT: tokenAuth mutation returns "str object has no attribute decode"

Django GraphQL JWT: tokenAuth mutation returns "str object has no attribute decode"

Currently I'm running a basic example of django-graphqljwt from the documentation page. https://django-graphql-jwt.domake.io/en/latest/quickstart.html

import graphene
import graphql_jwt


class Mutation(graphene.ObjectType):
    token_auth = graphql_jwt.ObtainJSONWebToken.Field()
    verify_token = graphql_jwt.Verify.Field()
    refresh_token = graphql_jwt.Refresh.Field()


schema = graphene.Schema(mutation=Mutation)

However if I run the tokenAuth mutation it throws me the below error in the GraphiQL interface. Note that if I enter incorrect credentials it throws an "Please enter valid credentials" instead of the below.

{
  "errors": [
    {
      "message": "'str' object has no attribute 'decode'",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "tokenAuth"
      ]
    }
  ],
  "data": {
    "tokenAuth": null
  }
}

Solution

I found this as an open issue on github for the django-graphql-jwt package and was able to resolve it by resorting to the 1.7.0 version of PyJWT. Currently installed was version 2.0
