I wanted to create an authentication for users using LinkedIn OAuth API and Firebase in my Android Application, but there are no options for direct authentication in Firebase Auth, but I found a solution from GitHub which was using Firebase Functions and Node.js
https://github.com/firebase/functions-samples/tree/master/linkedin-auth
I tried using this solution but after putting in the credentials in the linkedIn popup and clicking on submit button the error shows up saying "Error in the token Function: undefined" and in firebase console log it says "Function finished with status: 'crash'".
