Azure DevOps First Time Web App Deployment Always Gives Error - azure

Question

I am facing this odd situation. I have the following setup.
React JS app created using create-react-app
Code on GitHub
Azure Web App - Create from the Azure Portal.
Azure DevOps + Pipelines + YAML
I have been doing a bunch of deployments this week and I noticed this situation. Every 1st deployment, always ends up with the following situation inside the wwwroot folder.
But, every subsequent deployment, works just fine.
To reproduce
Create a new app with create-react-app
Put it on GitHub
Link GitHub repository with Azure DevOps Pipelines
Target the Pipeline to deploy to a Azure Web App, which has been created brand new.
The initial deployment, will always fail, with the above image. And, please, remember, Subsequent deployments dont fail.
So, the question is, is there something I can do to prevent this?
I am planning to automate resource creation on Azure, along with automating deployment.
Update 1
as per the comment, including my YAML here. I use this in all of my react JS deployments, which show the same issue as above.
trigger:
- master
pool:
vmImage: 'ubuntu-latest'
- task: NodeTool#0
inputs:
versionSpec: '10.x'
displayName: 'Install Node.js'
- script: |
npm install
npm run build
displayName: 'npm install and build'
- task: CopyFiles#2
inputs:
Contents: 'build/**' # Pull the build directory (React)
TargetFolder: '$(Build.ArtifactStagingDirectory)'
- task: PublishBuildArtifacts#1
inputs:
pathtoPublish: $(Build.ArtifactStagingDirectory) # dist or build files
ArtifactName: 'www' # output artifact named www
- task: ArchiveFiles#2
inputs:
rootFolderOrFile: '$(Build.ArtifactStagingDirectory)/build/'
includeRootFolder: false
- task: AzureWebApp#1
inputs:
azureSubscription: 'ReactJSRecipeAppConnection'
appName: 'ReactJSRecipeAppSep232020'
package: '$(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip'

Answer 1

FAILED TO INITIALIZE RUN FROM PACKAGE usually means the zip file is corrupted or not deflateable. Please check whether the WEBSITE_RUN_FROM_PACKAGE flag under App Service -> Application settings was set.
In addition, try to use task Azure App Service deploy v4, instead of task Azure Web App v1.

Answer 2

Taking off from the discussion about with #Cece Dong, here is what eventually worked for me.
trigger:
- master
pool:
vmImage: 'ubuntu-latest'
steps:
- task: NodeTool#0
inputs:
versionSpec: '10.x'
displayName: 'Install Node.js'
- script: |
npm install
npm run build
displayName: 'npm install and build'
- task: CopyFiles#2
inputs:
Contents: 'build/**' # Pull the build directory (React)
TargetFolder: '$(Build.ArtifactStagingDirectory)'
- task: PublishBuildArtifacts#1
inputs:
pathtoPublish: $(Build.ArtifactStagingDirectory) # dist or build files
ArtifactName: 'www' # output artifact named www
- task: ArchiveFiles#2
inputs:
rootFolderOrFile: '$(Build.ArtifactStagingDirectory)/build/'
includeRootFolder: false
- task: AzureRMWebAppDeployment#4
inputs:
appType: webApp
azureSubscription: 'RandomStuffReactJSConnection'
WebAppName: 'randomstuffreactjsappsept24'
package: '$(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip'
The above, I can confirm, no longer requires a second trigger for a proper deployment.
specifically, the usage of 'AzureRMWebAppDeployment#4' is what solved the original issue.
