🐛 Bug Report: Backstage Github auth is not working. about backstage

[joariasl]

This error also occurs when you don't have the User kind populated in the catalog. Don't forget add the githubOrg (Groups, Users) provider additional to the github provider (Repositories).

To avoid the undefined email problem with users with private addresses, invert the resolver evaluation to match the username first and the email after in the auth.providers.github.<env>

resolvers:
  - resolver: usernameMatchingUserEntityName
  - resolver: emailMatchingUserEntityProfileEmail
  - resolver: emailLocalPartMatchingUserEntityName

Do you need to set a profile.email?

Like so

apiVersion: backstage.io/v1alpha1
kind: User
metadata:
  name: tbeeren
spec:
  profile:
    displayName: TwanBeeren
    email: [email protected]
  memberOf: [guests]

Maybe this helps

Even after modifying this still the same issue. Can you helps me with further investigation. Due to this we are unable to proceed further implimentation

please remove the first 2 resolvers and keep only usernameMatchingUserEntityName:

        signIn:
          resolvers:
            - resolver: usernameMatchingUserEntityName

you need to pick the resolver that makes sense for your use case as described in https://backstage.io/docs/auth/github/provider/#configuration. Since the resolvers are used in order, emailMatchingUserEntityProfileEmail was the first one used, which requires the email of your users to be ingested in the users entities.

I've opened #24726. I hope it clarifies things.

The problem appears when a GitHub don't have configured the public email in his profile and his emails are marked as "Keep my email addresses private".
I've seen that setting up a GitHub App.

To solve that the user need:

1. Go to configure Public profile and select a "Public email". Save changes

2. If the email is not selected and you se the alert "You have set your email address to private. To toggle email privacy, go to email settings and uncheck "Keep my email address private.""
   Go to email settings and uncheck option "Keep my email addresses private".

   

Probably exists a different method con configure Backstage to match the private emails.
