How to enable google sign in?

[Darren120]

loginWithGoogle: async () => { const provider = new firebase.auth.GoogleAuthProvider(); try { const userCred = await firebase.auth().signInWithPopup(provider); return { user: userCred.user, }; } catch ( e) { return { error: e.message, }; } } <button onClick={async()=>await loginWithGoogle()}> GOOGLE </button>

the popup shows then exits

this is the error I get

code: "auth/auth-domain-config-required" message: "Be sure to include authDomain when calling firebase.initializeApp(), by following the instructions in the Firebase console."

Solved: make sure no spaces in your .env. I'm sorry guys I am new to nextjs

like

authDomain= abc

change it to

authDomain=abc
