Facebook OAuth - unable to log in

[roenfeldt]

As per the problem described in more detail on DevDojo, I have been trying to figure out what's preventing me from successfully make the social provider authentication functionality work. After digging deeper into the codebase, I ended up overriding the following:

• vendor/devdojo/auth/src/Models/SocialProvider.php,
• vendor/devdojo/auth/src/Models/SocialProviderUser.php,
• vendor/devdojo/auth/src/Http/Controllers/SocialController.php, and
• vendor/devdojo/auth/routes/web.php.

By debugging the private createSocialProviderUser() method of the SocialController.php Controller, I realized the following:

• assumming the email address returned by Facebook is not associated with an existing user in the app, Socialite is correctly returning the $user object along with its id, name, email, avatar, user, token, and expiresIn properties and their corresponding values from Facebook;
• the value of the $driver parameter of the createSocialProviderUser() method is correctly received as facebook;
• the $user->socialProviders()->create() call somehow fails, despite the fact that:
  1. 'provider_slug' => $driver // 'facebook'
  2. 'provider_user_id' => $socialiteUser->getId() // '9002[...]40[...]'
  3. 'nickname' => $socialiteUser->getNickname() // null
  4. 'name' => $socialiteUser->getName() // 'John Doe'
  5. 'email' => $socialiteUser->getEmail() // '[email protected]'
  6. 'avatar' => $socialiteUser->getAvatar() // 'https://graph.facebook.com/v3.3/9002[...]40[...]/picture'
  7. 'provider_data' // {"name":"John Doe","email":"[email protected]","id":"9002[...]40[...]"}
  8. 'token' => $socialiteUser->token // 'EAAPoOafsNc4BOZBnOaV6fDf4nMrSeQn7[...]'
  9. 'refresh_token' => $socialiteUser->refreshToken null
  10. token_expires_at' => $socialiteUser->expiresIn ? now()->addSeconds($socialiteUser->expiresIn) : null // 'Formatted: 2025-01-17 21:15:59 | Timezone: Europe/Copenhagen | Timestamp: 1737144959'

For some reason, the user doesn't get created, despite all the valid data as I mentioned above. Could one or both null values prevent the user from being persisted?

That is where I got stuck. Any help will be greatly appreicated.

Thanks a lot!

Hey!

Thank you for all of the additional information here!

I will look into this and keep you posted!

Hey Bobby,

I just realized something: each of my attempts to register a new user via the Facebook Social OAuth failed to create the user, yes, but the User model's IDs still kept being incremented in the DB.

After my many attempts with FB OAuth, today I registered a new user the normal Laravel Auth way, and it turns out that its id value is 45. I am positively certain that there were only two users (the default "Admin", and "Test 1"), created with Laravel Auth, when my FB OAuth implementation attempts started.

I'm not sure if this is normal SQL behavior, just wanted to bring more insight into the issue.

Hey @roenfeldt

I've tried to look into this further and reproduce it locally on my end but it all seems to be working as expected.

A couple of things that come to my mind:

• Regarding the empty log, can you confirm if you have APP_DEBUG=true set in your .env file? If not, can you set it and give it another try?
• What type of database are you using, is it SQLite or MySQL for example?
• Also in your browser web console, do you see any errors? You can try to: open the browser web console, then click on the register button and go through the flow and keep an eye on the console for any errors.
