Next-auth: Custom provider returns a Missing or invalid provider account

[JaredCE]

Your question
We run our own oAuth provider at work, and I'm trying to write an integration for it in next-auth, however i'm running into an issue when signing in where it's erroring with Missing or invalid provider account. having debugged the code, it seems to be missing an id on the providerAccount in the callback-handler.js.

What are you trying to do
Using this as my custom provider, I should be able to login to our own oAuth2 service.

{
      id: 'openimp',
      name: 'OpenImp',
      type: 'oauth',
      version: '2.0',
      accessTokenUrl: 'https://auth.example.com/oauth/token',
      authorizationUrl: 'https://auth.example.com/dialog/authorise?response_type=code',
      profileUrl: 'https://auth.example.com/api/userinfo',
      scope: [],
      params: { grant_type: 'authorization_code' },
      profile: (profile) => {
        return {
          username: profile.identifier,
          name: profile.cn + ' ' + profile.sn,
          email: profile.email,
        };
      },
      clientId: 'blah',
      clientSecret: 'secretblah',
    }

instead it returns an error of:

The providerAccount looks like:

{
  provider: 'openimp',
  type: 'oauth',
  id: undefined,
  refreshToken: undefined,
  accessToken: 'long token',
  accessTokenExpires: null
}

Is my code wrong, or is our oAuth2 service oncorrectly setup?

Hi there,

If you return the username as id from in profile function, that should resolve your problem!

profile: (profile) => {
  return {
    // Return Username as ID
    // username: profile.identifier,
    id: profile.identifier,
    name: profile.cn + ' ' + profile.sn,
    email: profile.email,
  };
},

Note: The ID can be a string or an int, it only needs to be unique to your provider.
