OAuth2 Authentication with Auth0

Hi, trying out connecting to our application using Auth0 OAuth2 authentication flows. I think I have it configured correctly, and when testing it, I’m seeing a change of page, but I’m getting an error message:

Here is the error: JsonWebTokenError: jwt must be a string

Anyone experiencing this issue?

To add additional context, I tried this once using Safari and I got the Authorization web form, but then it failed. Subsequently to that I now get this error message. I switched to Chrome and it seems to have authenticated correctly.

Final update, after confirming that everything is working in Chrome, I went back to Safari and it is also working properly.
