NextJs creating user document in mongodb after google sign in - reactjs

Question

i want to create a user document after i sign in with google in my nextjs application. I can sign in but it's not creating the document after it. This is my function
const handleSignIn = async () => {
try {
await signIn("google");
await addUser();
} catch (error) {
console.log("Erro");
}
};
The addUser function is
const addUser = async () => {
if (status === "authenticated") {
const user = {
name: session.user.name,
email: session.user.email,
avatar: session.user.image,
};
try {
await fetch("/api/new_user", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(user),
});
} catch (error) {
console.log(error);
}
} else {
console.log("Not logged in");
}
};
This is how i'm creating the new document in my new_user.ts file in the api folder
export default async function handleNewUser(req:NextApiRequest, res:NextApiResponse){
const client = await clientPromise;
const db = client.db("bookdb");
const coll: Collection = db.collection("users");
const user = req.body
console.log(user)
try {
await coll.insertOne(user)
res.status(200).json({response:'Success'})
} catch (error) {
res.status(500).json({error:'Erro'})
To make sure it was working, i triggered manually the addUser function after signing in and it worked.
What am i doing wrong here?

Answer 1

this is my snippet for google auth sign in with mongodb and nextjs using typescript and prisma.
signIn: async ({user, account}) => {
if (account?.provider === 'google') {
const googleAuthData = {
name: user.name,
email: user.email,
image: user.image,
authProvider: 'google',
password: ''
}
const exist = await prisma.user.findFirst({
where: {email: user.email},
});
if (exist) {
const result = await prisma.user.update({
where: {email: user.email},
data: {image: user.image},
});
} else {
const result = await prisma.user.create({
data: googleAuthData,
});
}
}
return true;
},
