WhatsApp-Web | How Whatsapp Web QR Code works | QRCode Processing library

I have deployed a multiconnect setup of the WhatsApp Business API client in Production Kubernetes enviroment, using the documentation for Minikube Developer Setup: Multiconnect on Minikube as referece.

But when doing the first login, in order to get the auth token, i get the following error on Postman:

Say I am building an instant messaging with app with React (I'm not doing that exactly, but this is easier to explain). I have a sidebar with a list of conversations and, when you click one, it is shown on the right (similar to this). I don't want to mount each conversation component until the user clicks it, but I don't want to unmount it, just hide it, when they click on another conversation. How can I do this cleanly? There will never be more than about 30 chats for any user.

I'm using nodemon in my nodejs project because I want whenever I made any changes it will restart automatically everything works fine but now problem is I want to use a lib which include puppeteer lib whenever I made any changes nodemon close the chromium browser and re-open it which take some time. This is making me slow in development. Is there any way I can stop this behaviour.

Here is my code.

Node.js app with Express, deployed on Heroku. It's just dynamic webpages. Loading static webpages works fine.

Loading dynamic webpages works on localhost, but on Heroku it throws me code=H12, desc="Request timeout", service=30000ms, status=503.

In addition, fresh after doing heroku restart or making a deployment, there always seems to be one instance of a status=200 that loads only the static portion of a dynamic webpage.

Screenshot of logs here.

I've tried the following, which have all led to either the same or other unexpected results when deployed on Heroku (such as Error R14 (Memory quota exceeded) and code=H13 desc="Connection closed without response"):

• Switching the Puppeteer Heroku buildpack I was using. I've tried the ones mentioned in this troubleshooting guide and this comment.
• Adding headless: true in Puppeteer's launch arguments.
• Adding the --no-sandbox, --disable-setuid-sandbox, --single-process, and --no-zygote flags in args of Puppeteer's launch arguments. (Reference: this comment & this comment)
• Setting the waitUntil argument in Puppeteer's goto function to domcontentloaded, networkidle0 and networkidle2. (Reference: this comment)
• Passing a timeout argument in Puppeteer goto function; I've tried 30000 and 60000 specifically, as well as 0 per this comment.
• Using the waitForSelector function.
• Clearing Heroku's build cache, as per this article.
• Printing the url variable (see my code below) in the console. Output is as expected.

I've observed that:

• With the code I have right now (see below), the try-catch-finally block never catches any error. It's always one of the following: I get an incomplete result (static portion of requested dynamic webpage), or the app crashes (code=H13 desc="Connection closed without response"). So I haven't been able to get anything out of attempting to print exception in the console from within the catch block.

Any ideas on how I could get this to work?

I am trying to build an electron react app. I need to integrate this node modules https://www.npmjs.com/package/whatsapp-web.js in my electron react app. My main.js of electron looks like this:

I am using whatsapp-web.js to send and reply message.

I can connect and reply message using following code:
