[AlbmaniaGroup]

Server operating system version

CentOS 7

Plesk version and microupdate number

18.0.48

First of all Merry Christams and hope you are enjoying the end of the year.
I am new on NodeJS and I have an app build in NodeJS. I have installed nodejs extension on plesk that came installed with phusion passenger server (never heard about it before). Now, I have deploied the software via GIT on the domain account, in a subdomain to be more precise, run the commands provided by documentation (composer install; some php artisa commands, npm run dev).Everything runs perfect with no errors, and when i try to load the page, it shows:

[ D 2022-12-25 21:42:37.1721 27069/T1 age/Spa/SpawnEnvSetupperMain.cpp:747 ]: shellName = 'bash' detected as supporting '-l': true

On NodeJS extensions, settings looks like this


I have to mention that the web app is working perfectly on localhost with the same settings but without Plesk. Also, have to mention that I have nGinx running as proxy.

Thank you

Hi, I am having the same problem here, after some investigation i found out that:
1. the error is generated from webpack compiler (angular ng build, in mycase)
2. dependency that still use the method self instead of this.

unfortunately, at this momenet, i am still struggling with this error, hopefully we'll find the way

You are not alone

- adding two files mentioned in the docs, .htaccess and index.html as self reference
- restart the node server

Hello there.
Thank you for your updates. Unfortunately we are not using Angular but pure node for react web app, and still struggling with the issue :-(
Thanks anyway for your help. I will check out that documentation whith the hope that I may find any clue to progress.

For anyone that may have the same issue, I have resolved it by Disableing the Node Application from plesk ("Disable Node.js" button as on the image attached above). Somehow, when it is enabled, it crashes something, so I have run all the commands on the terminal and left Node.js from Plesk GUI disabled. Everything works perfectly now. Hope it will help anyone.
