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.

I am using ngx-bootstrap 5.x.x in my Angular 8 project but now I have migrated my Angular v8 to v11 and I start facing issues with dropdown. It does not open on first click. I find they are recommended to use v7.0.0 but when I install it using

I need to upload a v8 heap dump into an AWS S3 bucket after it's generated however the file that is uploaded is either 0KB or 256KB. The file on the server is over 70MB in size so it appears that the request isn't waiting until the heap dump isn't completely flushed to disk. I'm guessing the readable stream that is getting piped into fs.createWriteStream is happening in an async manner and the await with the call to the function isn't actually waiting. I'm using the v3 version of the AWS NodeJS SDK. What am I doing incorrectly?

I was able to run my react app locally without issues, however when i deployed app to heroku I got OOM errors. It's not the first time I deploy the app, however this time I add OKTA authentication which apparently cause this issue. Any advise on how to resolve this issue will be appreciated.

I'm using Laravel 7.3 and need to update to 8 because of plugins needings

I'm reading the documentation but as I'm a noob as in English like in computing I have some errors and problems

First of all, I followed this :

Update the following dependencies in your composer.json file:

I'm new to this topic and i got stuck while reviewing a pseudo code thrown by a de-compiler.

I got this:

Hello great people of SO!

Sorry for bad english, but I will try my best to explain my issue

I'm using Laravel v8.x for my app, and after setting up model relationships, events, queues, etc, now I'm working for SQL

ATM, I have 2 Models,

• User belongsToMany User (Block)
• User belongsToMany User (Follow)
• Post belongsTo User

Database: 5 record for User 2 record for Block 3 records for Post

Table: (Using faker)

I would like to use purrr:map() and purrr:pluck() to apply data.table::fcase() rules to elements within a nested list and update the list by reference.

I can accomplish a working output using dplyr::mutate() but this output is in an unnested format and does not update by reference like data.table's := does.

Reproducible example

Question for v8 experts.

As we know, if the "shape" of the object does not change, v8 stores the object properties in a special array, and access them by index, which results in very fast access. I may be wrong on the details.

As described in this blog post from 2018, the size limit for this array is 1022.

Is this information still correct? Perhaps there were some improvements on this recently?

Thank you!
