@UsamaHaide0786 sorry for the situation you are having.

In the future, try to open one issue in the appropriate provider repository that you are having the issue with. It felt like spam opening the same messages 3 times.

Do you have any example repository that we can work with? What have you done so far to debug the situation? Do you have the basic skills to debug the situation and fix the issue yourself with our help?

Thanks for replying here is the repository I'm working on @yordis https://github.com/UsamaHaide0786/examle_chatapp

@yordis I'm not experienced enough to solve it by myself any help will be appreciated Thank you

[yordis]

What is the exact issue you are see in your console, or somewhere?

[yordis]

This is not an issue with Ueberauth, neither it is an issue with Ecto, but your code:

https://github.com/UsamaHaide0786/examle_chatapp/blob/d8ffb90cc73362db423b1cd601ee4edeabe61d54/lib/fchatapp_web/controllers/auth_controller.ex#L36

When auth.info.email is nil then it will fail. Check for nil values or don't use get_by or something else.

@yordis Thank you very much
