bcrypt.compare() Shows "data and hash arguments required" while testing the loginUser in Controller

[darshanjoshi16]

` export const loginUser = async(req,res)=>{

const {username,password} = req.body;

try 
{
    const user = UserModel.findOne({username:username})
   
    if(user)
    {
        const validity = await bcrypt.compare(password,user.password)

        validity? res.status(200).json(user): res.status(400).json("Wrong Password")
        

        
    }
    else
    {
        res.status(404).json("User does not exist");
    }
} 
catch (error) 
{
    res.status(500).json({message: error.message});
}

}`

This is the loginUser function..

while testing on thunderclient I am getting below error

I tried to check if anything is null because I have seen on on Stack Overflow. When I tried to get req.body.password as response which is passed through the Http request body. it is working but for the user.password which is stored in the database, it is showing the null. so it is where the problem but I cant figure out why it is happening?

Can Anybody Help? Thanks in advance
