How to fix bad input string error when connecting mongodb?

Question

JavaScript

When connecting the mongodb database, I get an error in my project. The most interesting thing is that if I create a separate file in which I execute the connection code, there will be no error. I even connected the same dependencies as in the main project, there was still no error, it is only in the main project file, the code of which I cannot post.
Here is my code to connect to the database:

mongoClient.connect("mongodb://localhost:27017/", {
        useNewUrlParser: true
    }, function(err, client) {

        if (err) {
            return console.log(err);
        }
        const db = client.db("db");
        const collection = db.collection("users");
        // взаимодействие с базой данных
       client.close();
    });
