I can´t deploy an angular app to my app service on azure because of FATAL ERROR Ineffective mark-compacts near heap limit Allocation failed

Question

Hi everyone,

I´ve been trying to deploy my angular application to azure web service (web app service).

Steps:

1. Use a build pipeline to generate an artifact (zip file) in Azure DevOps
2. Use a release pipeline that uses the previous generated artifact to deploy to my app service
3. An error occurs

Notes:

1. The zip file has a total size of 150MB
2. I have used 2 different tasks without any success (AzureWebApp@1 and AzureRmWebAppDeployment@4)

Can someone help me please ? Don't know if I'm doing something wrong or if there´s a known issue related to release pipelines

Hi @Bernardo Garza García

I can't imagine the zip file size being a contributing factor. I would try deploying the code directly to the app service via zip deploy, which you can do inside Visual Studio Code, or local git. This will help narrow down if it's your DevOps pipeline or your code repo.

The error message itself is pointing to memory allocation errors. I would caution to say you may hit the same issue using a different deployment method. Something else you could try is adjusting the memory limit via WEBSITE_MEMORY_LIMIT_MB application setting, changing the Node.js runtime, or upgrading to the latest Node.js version. If you're seeing positive results with that, then you can scale up your app service plan. You can also try to scale it back it down or create a separate app service plan just to see if you're getting the same deployment error.

If none of that is helpful, then we would need to work more closely with you regarding the matter. Please feel free to comment down below to let us know the outcome.
