Error running node application on Azure

Question

We are trying to run node application on azure. It get deployed successfully but when we try to run the application we get following error in trace logs.

ActivityId  {A5FF0B34-7C3F-4A99-9497-6C04A9AE9A9F}

Message: iisnode was unable to establish named pipe connection to the node.exe process before the process terminated

Any help will be appreciated.

Thanks.

Maybe the node process crashed due to an exception in your nodejs code? — minghan

You can download the diagnostic logs via the KUDU api at https://<your_site_name>.scm.azurewebsites.net/api/dump. And you can check the application logs in `\LogFiles\Application` folder. And if it is convenient, it is great if you can provide your key code snippets of raising the server. — Gary Liu

Get application logs using Gary's suggestion helped. Issue was with Azure env not understanding Babel commands like let etc. — nitinb

Gary's suggestion worked.

You can download the diagnostic logs via the KUDU api at https://<your_site_name>.scm.azurewebsites.net/api/dump. And you can check the application logs in \LogFiles\Application folder.

After looking at logs, the issue was that Azure services couldn't understand babel syntax.

Tried another node app without Babel, and it worked fine.

Additionally to the solution above:

Check if the configuration setting WEBSITE_NODE_DEFAULT_VERSION is set to the proper NODE Version.
