Hi, can anyone help me out with this error?
I'm getting this error when I'm trying to login using the facebook in thirdpartypasswordless recipe.

Hey. Does the fb ID you have contain the user’s email?

We require a user to have an email in order to sign in

and If the user is using their facebook account with phone number?

Won’t work by default. You will need to provide your own custom provider with fb which will add a fake email to the side based on the phone number.

I think people have done that in the past. See other discord threads.

would you be able to provide the python code for adding custom facebook login email change?

see the section in our docs about custom provider please. It has code snippets in python
