selectNodeVersion not working on Github Actions deploy

Deployment via Github Actions for an Azure web app fails on linux.

Here are my files:

My Github action:

The issue is that nodejs does not exist inside of /opt on the machine. I don't know how to get it there, or why it's not there, but I've experimented with new installs for node 18-lts and can confirm that with a new Azure Web App install this does not work.

Any help would be appreciated!

Thanks! We'll be in touch soon.

Same issue here, any help appreciated.

[talk2MeGooseman]

I am also having the same issue

[kodkroken]

Same issue here, we're trying to use node 18 for our custom deploy scripts which runs yarn install. However the packages we use require node version >= 16 since node 14 is now deprecated.

Hi @raph90 can you please check if you have this Env variable "SCM_SCRIPT_GENERATOR_ARGS" in your app settings and remove it before retrying?

[pniederlag]

Unfortunatly we do see this problem now as well. We didn't touch a thing. Latest success was in 2023-01, but when we tried our next deploy in 2023-07 we do run into troubles...

remote: Deployment Failed. deployer =  deploymentPath =  

we build and run on linux and try to find an (easy) way to ship our code from a jenkins-pipeline to azure function-app-runtime. git push was working from 2022-06(last time we had to overhaul our pipeline) until at least 2023-01

[pniederlag]

I found this to be part of .deployment in the repository and now have dropped it. Seems to help for me. Thx.

Glad that it helped @pniederlag. Let us know if we can close this.

[pniederlag]

@sgollapudi77 my problem seems solved @raph90 was original reporter, I have no clue wether he found a way to get his problem solved.

I'm hitting the same issue with a fresh App Service instance and the default custom deployment script for node.

Reproduction repo here.

[derhoppe]

Hi, we did solve this somehow. I really can't remember the full steps but we did create a .deployment file with this content:

[config] SCM_SCRIPT_GENERATOR_ARGS=--basic SCM_DO_BUILD_DURING_DEPLOYMENT=false ENABLE_ORYX_BUILD=false WEBSITE_NPM_DEFAULT_VERSION=6.14.15 command = bash deploy.sh

and we did change the deploy.sh by removing the selectNodeVersion line and adding these two lines:

# selectNodeVersion NPM_CMD=npm NODE_EXE=node

Now it works for us.

Maybe that helps someone here...

Hi

If the problem persists and is related to running it on Azure App Service, please open a support incident in Azure: https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request

This way we can better track and assist you on this case

Thanks,
