Can't find custom claims in idToken

I’m trying to add roles as a custom claim in user’s idToken. I’m running the following post-login action.

exports.onExecutePostLogin = async (event, api) => {
  const namespace = 'https://my-app.example.com';
  if (event.authorization) {
    api.idToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles);
    api.accessToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles);
  }
}

I’m checking for it like this on my dashboard component.

  const { user, isLoading, error} = useUser();
  if (user){
    console.log(user['https://my-app.example.com/roles'])
  }

It’s returning undefined.

Hi @melek

Welcome to the Auth0 Community!

I have attempted to reproduce the issue on my end however everything works as expected.
This is the console log in my application:

And this is the claim inside the token:

I would recommend you to review our documentation regarding creating custom claims and to check if you are respecting our namespace guidelines.

If you have any other questions, feel free to leave a reply!

Kind Regards,

Hi @nik.baleca,

I don’t think the issue is with the namespace as I’m using the exact same namespace https://my-app.example.com/

I see

Could you let me know what SDK/Sample app are you using?

Kind Regards,
Nik
