AshAuthentication Auth0 error after setup instructions

I followed the AshAuthentication Auth0 guide

My understanding is that it needs to be followed after following the AshAuthenticationPhoenix guide.

The guide did not say which code to delete.

I deleted the hashed password code, because I will no longer use that.

I also deleted the Token resource and all references to it, because my understanding was that it’s purpose is to be a password reset token, which my app will no longer handle.

This is the PR I ended up with

Password auth works on the main branch, so this should just be the diff from password auth to Auth0.

Right now I get redirected to Auth0, redirected back to my app, but an error gets rendered on the redirect url.

Here is the stack trace:

We should definitely make the error for this include more context. The action is referring to an :identity called :email, but the identity that you have on your resource is called :unique_email.

upsert_identity :email

You’d want to change that to

upsert_identity :unique_email

EDIT: the line: Auth0 almost working 🤷‍♂️ by dewetblomerus · Pull Request #2 · dewetblomerus/red · GitHub

That did it @zachdaniel :heart:

Now I can sign in and out with Auth0! :partying_face:

Here is the resulting diff if anyone is interested.

The error makes perfect sense now that I see the fix, but it would be difficult for someone new to Ash to realize that. I just wrongly assumed upserting with email must be right because there is an email column in the DB.

Yeah, absolutely. It should say something like:

No identity found for Red.Accounts.User called :email.

Resource.action required this identity due to using `upsert_identity :email`

Available identities:

* `identity` ...
