mongoose find with filter on enum not returning results

Question

I have mongoose schema as given below;

var UserSchema = new Schema({
    //...
    pets: {type: String, enum: ["Cat", "Dog", "Bird", "Snake"]}
    //...
});

// create a new user
const user = new User({
    fullname, email, pets:"Cat"
});
try {
    await user.save();
    res.send({ "success": true, user});
} catch (err) {
    res.json({ success: false, message: "Could not add User!", error: err });
}

// to fetch users
const users = await User.find({pets:'Cat'});
res.json({ 'success': true, users });

The response is always empty users array while i have data in db of users having pets value as Cat

{
    "success": true,
    "users": []
}

Can someone please guide me what's wrong here? or how to get the results with pet as Cat? Thanks in advance.

The problem was with data, i dropped the collection and it started working.
