Application Error in App Service

Application Error in App Service

Aniket Kumar 0

I have created a DevOps pipeline for deploying a Nodejs Application on App service. The pipeline works well but when browsing the URL of the app service, it shows an error. I can't able to resolve this issue after seeing the app service logs.

App Service Logs:

2023-02-09T11:23:00.767Z INFO - Logging is not enabled for this container.

Please use https://aka.ms/linux-diagnostics to enable logging to see container logs here.

2023-02-09T11:23:05.590Z INFO - Initiating warmup request to container static-webapp-devops_0_86004dba for site static-webapp-devops

Anyone, please help me in solving this issue.

Hi @Aniket Kumar , the snippet you included is from your docker logs the ends in _docker.log and is logging the overall container, in this case that your container app failed respond to HTTP request. This normally happens because of an application failure or port misconfiguration. You need to open the log file ending in _default_docker.log which contains the logs from your application code. It should indicate what errors popped up during application startup.

Hi, @Ryan Hill I have resolved this problem.

Now, I am facing another issue.

Issue - The zip file deployed to /wwwroot folder in the app service is not there.

I am using the below pipeline yaml:


# Node.js
# Build a general Node.js project with npm.
# Add steps that analyze code, save build artifacts, deploy, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/javascript

trigger:
- main

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: NodeTool@0
  inputs:
    versionSpec: '16.x'
  displayName: 'Install Node.js'

- task: Npm@1
  inputs:
    command: 'install'

- task: CopyFiles@2
  inputs:
    SourceFolder: './'
    Contents: |
      **\*.js
      **\*.json
    TargetFolder: './'
    CleanTargetFolder: true

- task: ArchiveFiles@2
  inputs:
    rootFolderOrFile: '$(Build.BinariesDirectory)'
    includeRootFolder: true
    archiveType: 'zip'
    archiveFile: '$(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip'
    replaceExistingArchive: true

- task: PublishBuildArtifacts@1
  inputs:
    PathtoPublish: '$(Build.ArtifactStagingDirectory)'
    ArtifactName: 'drop'
    publishLocation: 'Container'

Is there any part I am missing in this yaml configuration?
