How to save the Reset Password Nodejs and MongoDb - node.js

Question

I am using SendGrid to send the user the reset password link that goes with two parameters (The user._id and token). I have another component that saves the user's changed the password but all I get is an error user. save is not a function
Email helper Code.
import sendGrid from "#sendgrid/mail";
export class sendGridEmail {
static async sendResetPasswordEmail(email, token, id) {
sendGrid.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: `${email}`,
from: `${process.env.VERIFIED_SENDER}`, // Change to your verified sender
subject: "RESET YOUR PASSWORD",
text: `Follow this link to reset your password: ${process.env.BASE_URL}/${id}/${token}`,
};
return sendGrid
.send(msg)
.then(() => {
console.log(`password rest link has been sent to: ${email}`);
})
.catch((err) => {
console.log(err);
});
}
sendLink Component
export const resetUserPassword = asynchandler(async (req, res) => {
const { email } = req.body;
const user = await userModel.findOne({ email });
if (!user) {
res.status(404);
res.json({ message: "the email provided was not found" });
} else if (user) {
const token = AuthToken(user._id);
try {
await sendGridEmail.sendResetPasswordEmail(user.email, token, user._id);
res.status(200);
res.json({
message: `a link to reset your password has been sent to: ${user.email}`,
});
} catch (error) {
res.status(500);
res.json({ message: error });
}
} else {
res.status(500);
res.json({ message: "Internal Server Error" });
}
});
The Component that tries to update the password in the Database but I get an error user.save() is not a function
export const saveResetPassword = asynchandler(async (req, res) => {
const { id, authorization } = req.params;
const user = userModel.findOne(req.params.id);
const private_key=process.env.PRIVATE_KEY
const payload = jwt.verify(authorization, private_key);
if (user._id === id || payload.id) {
try {
user.password = req.body.password;
await user.save();
} catch (error) {
res.status(404);
res.json({ message: `an error occured: ${error}` });
}
}else{
res.status(500)
res.json({message: "an error occured"})
}
});
My Routes
import { loginUser, registerUser, resetUserPassword, saveResetPassword } from "./controllers/user.controller.js";
export const Routes =(app)=>{
app.get("/health", (req,res) => {
res.send(200).json({message:"Server health check is Ok"});
});
// user api's
app.post('/api/registeruser', registerUser);
app.post('/api/loginuser', loginUser);
app.post('/api/password-reset', resetUserPassword);
app.post("/api/save-password/:id/:authorization", saveResetPassword);
}

const user = await userModel.findOne(req.params.id);
You forgot await, model.findOne() returns a Promise
