NodeServer | Node project based on MVC Framework | Model View Controller library

I'm using the SeleniumGrid in the most recent version 4.1.2 in a Kubernetes cluster.

In many cases (I would say in about half) when I execute a test through the grid, the node fails to kill the processes and does not go back to being idle. The container then keeps using one full CPU all the time until I kill it manually.

The log in the container is the following:

I need to make unit tests for some post requests but i dont understand how.I tried with mswjs but the test passes because i'm missing something and i dont know what.I tried to test the requests in an usual way but i wasnt able to put my conditions there and it was sending only 200 status code..
To start with,this is my folder structure:

I have a volume which contains data that needs to stay persisted. When creating the volume for the first time, and mounting it to my node container, all container contents are copied to the volume, and everything behaves as expected. The issue is that when I change a few files in my node container, I remove the old image and container, and rebuild them from scratch. When running the updated container, the container's files don't get copied into the volume. This means that the volume still contains the old files, and therefore when the volume is mounted in the container, no updated functionality is present, and I have to remove and recreate the volume from scratch, which I can't do since the volume's data needs to be persisted.

Here is my dockerfile

I'm trying to wrap my node express backend with Docker. However, when running my docker-compose file. I encountered error when running npm install stage throughout the dockerfile, saying it doesnt found the package.json copied in my local directory to the directory inside my container. Below is my project directory structure. Trying to proxy my node express backend API using nginx. Any sources that can help what I'm trying to achieve much appreciated.

error log:

Trying to set up selenium 4 grid with the below docker-compose file but getting the "Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure" error and need some help to fix the same.

docker-compose file:

I've got a nodeserver and I'd like to start everything it depends on before launching it. The package runs on windows but depends on a multi-container docker setup in WSL.

So I've tried

I have a C# Winform application trying to launch a node server.

However the code for this is written in a different cs file, Class1.cs rather than in Form.cs itself. I need to keep this separated in different files. Below is my Class1.cs file:

I've looked but haven't been able to find a solution to this specific problem, so I thought I'd ask. I'm a novice javascript developer who clearly needs to read more about scope, callbacks and promises.

I'm trying to nest callbacks to get data out of a http request using the fetch API in javascript. At this point in my project, I've sent data to a node back end, called a few apis, then sent json data back to the client.

I now want to access that data outside of the function getServerData in the below.

I've tried a few different things but haven't been able to figure it out. I feel like I'm missing something obvious.

My current code is below:

Is there a way where I can save a timestamp out of my application / object, so when I restart the nodeserver I can get that value?

I need this for my cronjob. I need to save the last synching even though I restart the server.
