in signin page code onclick code is not provided

for eg:
If Harkirat is logged in, then he should not see his name coming in the dashboard, it will be stupid if that person is sending money to himself only,

How to tackle this while getting all the users except the user who is logged in?

if i am making a transfer from one account to another then the request successfully returns the "Transfer Successful" message but the balance in the Database is not getting updated.
PS:
i have already tried the promise.all and findByIdandUpdate and findOneandUpdate nothing changes.

In backend->routes->user

await User.updateOne(req.body, {
    id: req.userId
})

res.json({
    message: "Updated successfully"
})

updateOne takes filter as the first argument and updated information as the second argument, but opposite is been done here.

Whenever we are creating new user, the user's password should be hased before saving to the database

the error im getting is :SyntaxError: Unexpected end of JSON input
