Unauthorized while trying to translate a field

[tombreit]

In an non-production wagtail installation I get an Unauthorized exception even when logged in as a superuser:

[08/Jun/2021 17:04:01] "GET /admin/pages/13/edit/ HTTP/1.1" 200 21405
[08/Jun/2021 17:04:01] "GET /admin/localize/jsi18n/ HTTP/1.1" 200 3187
Unauthorized: /admin/localize/translate/5/strings/11/edit/
[08/Jun/2021 17:04:10] "PUT /admin/localize/translate/5/strings/11/edit/ HTTP/1.1" 401 58

when trying to translate a field:

I'm sure I've translated some pages successfully some time ago...

I'm now on wagtail 2.13.1 and wagtail-localize 0.9.5, but this error was already present in 2.12.x

Sorry for the noise - this issue was caused by my root rest_framework settings:

# project settings.py

REST_FRAMEWORK = {
    ...
    'DEFAULT_AUTHENTICATION_CLASSES': [
         'rest_framework.authentication.TokenAuthentication',
    ]
}

After moving/deleting this setting fields could be translated again.
