Description

Following this tutorial:
https://auth0.com/docs/quickstart/backend/golang#validate-access-tokens

validating custom claims is no longer working.
I can validate the jwt but cannot get custom claims.

Reproduction

Repoduce steps:

1. Setup an auth0 api describe here: https://auth0.com/docs/quickstart/backend/golang#create-an-api
2. git clone org-18199888@github.com:auth0-samples/auth0-golang-api-samples.git
3. create a .env file in the root of the cloned project with the api from above
4. This token was grabbed from: https://manage.auth0.com/dashboard/us/dev-aelumhqjxjwyvowv/apis/65340d421cfbcc839d0af2ed/test

curl --request GET \                                                                                                                                                                                      FeatureFlagging
 --url http://localhost:3010/api/private-scoped \
 --header 'authorization: Bearer SOME_TOKEN

5. response {"message":"Insufficient scope."}

Additional context

Theres even a section that lets you examine the jwt from the dashboard but says scopes

{
  "iss": "https://dev-aelumhqjxjwyvowv.us.auth0.com/",
  "sub": "ZXfvxk0RCZFjwJyRkCTGp5JJi1nFaf69@clients",
  "aud": "http://backend/",
  "iat": 1697985763,
  "exp": 1698072163,
  "azp": "ZXfvxk0RCZFjwJyRkCTGp5JJi1nFaf69",
  "gty": "client-credentials",
  "permissions": []
}

I was able to get this example working, but updating the docs would help people in the future.

First you need to enable RBAC and Permission under API settings

Then you need to specifically enable the permissions under applications > machine user > apis
the select permissions you want to send

Then they will finally show up

{
  "iss": "https://dev-aelumhqjxjwyvowv.us.auth0.com/",
  "sub": "ZXfvxk0RCZFjwJyRkCTGp5JJi1nFaf69@clients",
  "aud": "http://backend/",
  "iat": 1697988893,
  "exp": 1698075293,
  "azp": "ZXfvxk0RCZFjwJyRkCTGp5JJi1nFaf69",
  "scope": "user:read read:appointments",
  "gty": "client-credentials",
  "permissions": [
    "user:read",
    "read:appointments"
  ]
}

Thanks for raising this @josh-bell-colab, had you created your API through the quickstart or were you using an existing one? I wonder if we can simplify the setup there

[josh-bell-colab]

Yeah I was following this quick start, which doesnt mention these steps:
https://auth0.com/docs/quickstart/backend/golang#create-an-api
