Describe the issue

Just want to report a bug with Instagram authentication. Aparently there's a unknown field on the signIn callback that's causing a error on signIn. I manage to fix it but I would like to warn everybody here.

I notice the error when trying to login with Instagram. This error apeared:

Then I decided to console.log every callback on next auth and host my app on Vercel to watch for error logs:

And this error apeared on signIn:

How i fixed:
I deleted the field user_id on account

Extra if needed:
This is my prisma schema (the default one)

How to reproduce

Use Instagram for authentication

Expected behavior

Login without errors

Hi 👋 this is due to user_id is not defined in the schema. You could either include it or map it to the current userId. Admittedly this is not ideal, that's why we're working on #5461 to make it easier for developers. Closing 🙌

Seems like this issue is still present. In the case of Instagram, it has both user_id and userId, so removing user_id seems like the correct fix.

I modified my PrismaAdapter to fix this, but might be worth taking a look at it in the code adapter itself:

// authOptions config

adapter: {
    ...PrismaAdapter(prisma),
    linkAccount(data) {
      const modified = { ...data };
      if (modified.user_id) {
        if (!modified.userId) {
          modified.userId = modified.user_id as string;
        }
        delete modified.user_id;
      }
      return PrismaAdapter(prisma).linkAccount(modified);
    },
  },
