proposal-numeric-separator | A proposal to add numeric literal separators in JavaScript | Math library

I Know that there is a lot of topic about this, but since none of them work, I must make a new one, I'm quite confused as why my electron app doesn't launch when I used yarn dev for my project, but when my friends try it, in his laptop, he can run and the apps launch normally without any problem, so Is there anyone here ever face the same problem with me? if there is someone, how can you solve this problem?

this is what my terminal looks like:

for information I used:

I have migrated Webpack v4 to v5, made changes relative to documentation and deprecation messages from CLI, and got successful build, though during the application testing I noticed that JavaScript doesn't run and there are no errors. I am getting plain html rendered by SSR.

Have no clue why it doesn't work, because it's silent, maybe misconfiguration issue.

Here is my webpack configuration:

I'm getting an error when running npm test. I feel like I have tried every existing suggestion online, but I can not get it to work.

Here is my package.json. I thought the "transformIgnorePatterns": [ "/node_modules/(?!@total/*)", ], would solve the issue, but it didn't.

I've recently added @babel/helper-annotate-as-pure to my list of babel plugins:

I'm trying to create a build for this project but I've faced this issue with babel :

Here's the piece of code where it's complaining about:

I've been trying to run my nuxt app in docker and the build seem to work for the most part other than it keep missing core.js dependencie. I've tried adding core-js manually, babel, tried to run the suggested install command in the error, but to no help.

Dockerfile:

I have successfully deployed this app before but now when I try to deploy new code I get an H10 error as soon as I request the app from the browser.

Log from heroku logs --tail

Things I've tried so far:

• Checked express is listening for process.env.PORT and not "process.env.port"
• heroku restart
• heroku local web which works just fine
• Checked that any environment variables that I am using are set in the heroku config
• Checked dependencies (to be honest, I'm not 100% sure if I missed anything)
• Deleted Heroku dyno instance and created a fresh deploy

Appreciate any and all help. Thanks.
