Unable to get custom claims to work with WPF projects (Access Token) Please help!

Help

I have been trying all day to get this to work. I have a WPF application and authentication works just fine. However I need to be able to know the role of the user or permissions. I have tried to add custom actions and then add it to the login flow. However, every time the Access token and/or the ID token just has the normal OpenID/Profile/Email claims and nothing more.

For some reason I have tried everything. Here is my coding below.

Auth0 Custom Actions/Flow

exports.onExecutePostLogin = async (event, api) => {
const namespace = ‘https://XXXXXX.us.auth0.com’;
if (event.authorization) {
api.idToken.setCustomClaim(${namespace}/roles, event.authorization.roles);
api.accessToken.setCustomClaim(${namespace}/roles, event.authorization.roles);
}
};

And here is the call within the WPF.

Auth0ClientOptions clientOptions = new Auth0ClientOptions
{
Domain = “XXXXX.us.auth0.com”,
ClientId = “XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX”,
Scope = “openid profile email offline_access”
};
clientOptions.PostLogoutRedirectUri = clientOptions.RedirectUri;

var client = new Auth0Client(clientOptions);

var loginResult = await client.LoginAsync();

Hi @demariners !

Could you please try using backquotes ` for the namespace identifier in your Action code? It has to be a string.

exports.onExecutePostLogin = async (event, api) => {
const namespace = ‘https://XXXXXX.us.auth0.com’;
if (event.authorization) {
api.idToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles);
api.accessToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles);
}
}

Please let us know if that worked!

That did not work sadly. Is there anything specific I need to put in the scope?

exports.onExecutePostLogin = async (event, api) => {
const namespace = https://XXXXXX.us.auth0.com;
if (event.authorization) {
api.idToken.setCustomClaim(${namespace}/roles, event.authorization.roles);
api.accessToken.setCustomClaim(${namespace}/roles, event.authorization.roles);
}
};

exports.onExecutePostLogin = async (event, api) => {
  const namespace = `https://deflight.us.auth0.com`;
  if (event.authorization) {
    api.idToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles);
    api.accessToken.setCustomClaim(`${namespace}/roles`, event.authorization.roles);
  }
};

I also noticed if I type:

https://XXXXX.us.auth0.com/roles

Into my browser I get not found. Not sure if that is because I need to be authenticated or not but just noticed that.

@demariners , thank you for following up!

This is the namespace identifier and it doesn’t have to be a valid URL.

You should be good with the code snippet I shared. When testing with a test user, please make sure the user has a role assigned.

On your Auth0 tenant, I noticed the only Action applied to the Login flow is the one that adds email address of a logging in user as a claim.

Please also remember to deploy the action once it’s ready. You can have several Actions added to a single flow.

Please let us know how that goes!
