I have implemented Facebook login on my website. It works perfectly well on my Facebook account which has been registered with email address.
So when ever I log in using Facebook on my website it successfully returns the email address from my Facebook and insert the information into my local database. Similarly I used other Facebook account that was registered with an email address but it does not return the email address to my website.
My application is built using AngularJS 1.6 and Laravel. Your task is to identify and rectify the issue and must be willing to work remotely.
