​OIDC login with Microsoft Entra fails on Zod

[chief-nerd]

What happened?

Trying to make OIDC work with Microsoft Entra ID.

AFFiNE.use('oauth', {
  providers: {
    oidc: {
      // OpenID Connect
      issuer: 'https://#.microsoftonline.com/<tenant_id>/v2.0',
      clientId: '<app_id>',
      clientSecret: '<app_secret>',
      args: {
        scope: 'openid email profile offline_access',
        claim_id: 'preferred_username',
        claim_email: 'email',
        claim_name: 'name',
      },
    },
  },
});

Anything else?

Permissions in Entra ID are set:

[forehalo]

you set preferred_username as claim_id but the content of user returned by your provider's endpoint doesn't contains such field

[chief-nerd]

Yea so turns out MS does not support that field.
Who thought.

Can I choose any other one? Like email ?
Any best practices from your side?

Much appreciated you took the time.
