I am doing my projects with no errors, but suddenly server-side crashes and the error is "BSONTypeError: Argument passed in must be a string of 12 bytes or a string of 24 hex characters or an integer"
I have tried other suggestions for this similar problem from StackOverflow but it's not working.
I have attached- const ObjectId = require('mongodb').ObjectId;
but not solved yet. The full error of code is
var _this = _super.call(this, message) || this;

const items = await eventsCollection.findOne(query);
res.json(items);
There is no input validation in your code, but you cannot assume that req.params.id always is a valid ObjectId.
You can modify the route path to make sure that the route handler only accepts something that looks like a valid ObjectId:
app.get('/events/:id([0-9a-fA-F]{24})', async (req, res) => { … });
