Is there any way to extend the class Auth0User in order to pass additional fields to the payload? (e.g. custom field)

[luciano-buono]

class Auth0User(Auth0UserBase):
    roles: list[str] = Field(None, alias=f'{settings.auth0_rule_namespace}/roles')  # type: ignore [literal-required]

I would like to extend your class Auth0 with an additional roles field, which I have added to my JWT The main goal is to be able to obtain this field from the JWT passed through the request

@app.get("/api/get_auth0_user")
def get_secure(user: Auth0User = Security(auth.get_user)):
    return {"message": f"{user}"}
## Here it would display id, permissions, email, and roles

Besides the fact that reading roles in the backend is an anti-pattern (except if used only for literal display purpose), instead of relying only on granular permissions, yes it's possible to extend, you're already done the python / fastapi part.

However, in order for that to work, you need to use auth0 actions to add the roles as custom claim to the jwt. A few lines of javascript code will be required in your auth0 console.

Hi, yes I have already done that Action Flow in the login for Auth0

I needed to extend not only Auth0User, also Auth0 class in my own file
