Hey, I am working on putting up a rocket rest api with a mongodb database.

I have been able to create a successful connection to the MongoDB Atlas and put the resulting client into the state management of rocket via the manage builder function like this:

I have a react application (Node back end) running on Heroku (free option) connecting to a MongoDB running on Atlas (also free option). When I connect the application from my local machine to the Atlas DB all is fine and data retrieved (all 108 K records) in about 10 seconds, smaller amounts (4-500 records) of data in much less time. The same request from the application running on Heroku to the Atlas DB fails. The application running on Heroku can retrieve a small number of records (1-10) from the same collection of (108 K records), in less than a second. As soon as I try to retrieve a couple of hundred records the system fails. Below are the logs. I included the section of the logs that show a successful retrieval of 1 record and then failing on the request for about 450 records.

I have three questions:

1. What is the cause of the issue?
2. Is there a work around in the free option of Heroku?
3. If there is no work around in the free option, what Heroku pay level will I need to get to and what steps will I need to take to get this working? I will probably upgrade in the future but want to prove all is working before going in that direction.

Hy, I start learning a nodejs with restapi. But I'm trying to connect my mongodb atlas but it is giving me that error:

I have a problem when I try to update or delete data from my MongoDB Atlas database.

The thing is, it looks like the "updateOne" and "deleteOne" methods are being called but not in the right way.

Whenever I try to retrieve the operation the result is the following:

I was following this tutorial (https://docs.microsoft.com/en-us/learn/modules/create-your-first-iot-central-app/) In unit 4, I followed all the steps but what I could see was just a blank page like this

I would like to do a range search on a date using MongoDB Atlas Search, but I also need to include search results where there is no date at all. This is how I would do this in a $match stage of an aggregation pipeline:

Pretty much the question. Here's what I have currently:

Here my server side code

I'm trying this tutorial from youtube:

so far I have a server listening on port 8080 I'm connected to MongoDB atlas database and it worked fine, my next step is to make an API to do signup so here's my code:
