Custom rule to add user.app_metadata to accessToken does not trigger

Help

Greetings,

I set up a custom rule to add user.app_metadata to the accessToken, which I retrieve when logging in.
I did not set any other configuration as I assume that rules work on every request when they are enabled.

I use the auth0-js client library and can successful login and retrieve a accessToken.

This is my rule:

function (user, context, callback) {
 const namespace = "https://my_namespace/"; // my_namespace is a placeholder...

  context.accessToken[namespace + "app_metadata"] = user.app_metadata;

  callback(null, user, context);
}

This is my client setup:

const auth0Client = new auth0.WebAuth({
    domain: config.AUTH0_DOMAIN,
    audience: "https://${config.AUTH0_DOMAIN}/userinfo",
    clientID: config.AUTH0_CLIENT_ID,
    redirectUri: config.AUTH0_REDIRECT_URL,
    responseType: "id_token",
    scope: "openid profile email",
});
auth0Client.authorize();

Hi @glennydc,

Are you sure you are getting an access token and not an ID token? I believe you need to specify token in your response type if you want an access token.

Otherwise, your rule looks fine to me. This is my template rule for that use case:

Soooo it’s 2023 and this month I loaded up my project which uses exactly that template you shared @markd except my metadata is now missing!?

I literally ran this same project about three weeks ago and it was fine.

Has some breaking change come through and done the nasty?

Interesting… my namespace had /custom at the end. I removed it to see what would happen and now the metadata is back.

I’ve made no other changes. Weird.

So I changed the namespace (removing “/custom” off the end) and my frontend code to suit, and it worked again.

Then I changed both back to the original namespace I had and it’s still working, just like it used to.

Did the rule just stop getting processed or something, until I started making changes and then it kicked in again?

Little concerning :face_with_raised_eyebrow:
