Unable to get facebook to authenticate...

[mreaybeaton]

Question 💬

I am having some trouble getting facebook to authenticate. I am using standard nextjs-auth. I get the following error:

I am using localhost:3000 and my setup for facebook login is as follows:

my understanding is facebook login does not require redirect url's for localhost? I tried anyway but the field doesn't accept localhost unless you add httpS://localhost

Node v16.13.2
npx v8.1.2
yarn 1.22.17

I created this project with yarn create and the app is standard.

Please let me know if you need any more details. I have tried various difference combinations of trying to add localhost, facebook, the redirect url into various domains in the facebook app, but nothing I have tried seems to work.

I am using firebase as a backend and I went as far as enabling facebook authentication on their to give me a redirect url (as localhost doesn't work), but that also didn't work either.

I imagine it's something very silly I am missing.

How to reproduce ☕️

Create a nextjs app with yarn, add nextjs-auth, create a facebook app.

No, I am afraid I cannot help regarding this.

Make sure you are trying to login using your developer account , if you use any other account to login in localhost you will get this error .

BUT for me it started 2 days ago even with developer account logging on localhost i get expected 200 OK, got: 400 Bad Request, name: 'OAuthCallbackError'

Fore sure, I'm using the test account generated in the settings.

Don't use the test account that has been generated , use the facebook account you registered your app with facebook.

Any news on this? I am currently dealing with same issue? Any idea what this could be related to?

edit: I just figured out that I had created a "Business" type app instead of a "Consumer" one. When using next-auth with a Consumer type app, it works for me. However, I do want to use a Business type app, as I want to use Instagrams GraphAPI.

Should I be able to use next-auth for this? Or does it only work with Consumer type apps?

[viperxeyes]

It does work with any kind of app you choose, when you register for facebook developer any login attempt with any account other than the developer account will result in this error.

example: you sign up for facebook with [email protected] , then you go to facebook developer and register for [email protected] ,you add the facebook login to your app , now you won't be able to to use facebook login except with [email protected] , any other account will result in this error page , unless you move to production by ticking the switch button in the app setting which require verfication and other stuff.

Thanks for your reply, but I don't think that's it in my case.

Been using my developer account to login, I haven't even created other accounts.

me too, not in my case

I'm dealing with the same issue. Is it possible to use the NextAuth to login to Facebook and from there use the marketing API from Facebook? To use the marketing API I forcefully need to create an app of the type Business by the way.

I want to do the same, did you do it? How?

https://yourdomain.com/api/auth/callback/facebook <--- change yourdomain.com to your production domain.. and put that into the allowed URI on facebook settings....
