You can create middleware to resolve the error

const errorHandler = (err, req, res, next) => {
 let statusCode = res.statusCode === 200 ? 500 : res.statusCode;
 let message = err.message;
 if (err.name === "CastError" && err.kind === "ObjectId") {
  statusCode = 404;
  message = "Resource not found";
 }
 res.status(statusCode).json({
  message,
  stack: process.env.NODE_ENV === "production" ? null : err.stack,
 });

 next();
};

module.exports = { notFound, errorHandler };


And use it to your main index (server file).js.
