Azure Pipeline Errors When Deploying Azure Functions

Solution

Change the DeploymentType to webDeploy in the AzureRmWebAppDeployment@4 task. This deployment method preserves all native binaries, including CEF, during the deployment process.

Also set zipAfterPublish: false in the publish step so the output folder is not zipped before deployment.

The following pipeline YAML shows the complete recommended configuration:

jobs:
  - job:
    steps:
    - checkout: self
      displayName: Checkout Repository
      lfs: true

    - task: AzureCLI@2
      displayName: Check Azure CLI Installation
      inputs:
        azureSubscription: '<your-azure-subscription-name>'
        scriptType: 'ps'
        scriptLocation: 'inlineScript'
        inlineScript: 'az --version'

    - task: DotNetCoreCLI@2
      displayName: Restore Function Project
      inputs:
        command: 'restore'
        projects: '<path-to-your-csproj>'

    - task: DotNetCoreCLI@2
      displayName: Build Function Project
      inputs:
        command: 'build'
        projects: '<path-to-your-csproj>'
        arguments: '--configuration Release --no-restore --verbosity normal'

    - task: DotNetCoreCLI@2
      displayName: Publish Function Project
      inputs:
        command: publish
        arguments: '--configuration Release --no-build --output $(Build.ArtifactStagingDirectory)/publish_output'
        projects: '<path-to-your-csproj>'
        publishWebProjects: false
        modifyOutputPath: false
        zipAfterPublish: false

    - task: AzureRmWebAppDeployment@4
      displayName: 'Deploy Azure Function App'
      inputs:
        ConnectionType: 'AzureRM'
        azureSubscription: '<your-azure-subscription-name>'
        appType: 'functionApp'
        WebAppName: '<your-azure-function-app-name>'
        enableCustomDeployment: true
        DeploymentType: 'webDeploy'

jobs:
  - job:
    steps:
    - checkout: self
      displayName: Checkout Repository
      lfs: true

    - task: AzureCLI@2
      displayName: Check Azure CLI Installation
      inputs:
        azureSubscription: '<your-azure-subscription-name>'
        scriptType: 'ps'
        scriptLocation: 'inlineScript'
        inlineScript: 'az --version'

    - task: DotNetCoreCLI@2
      displayName: Restore Function Project
      inputs:
        command: 'restore'
        projects: '<path-to-your-csproj>'

    - task: DotNetCoreCLI@2
      displayName: Build Function Project
      inputs:
        command: 'build'
        projects: '<path-to-your-csproj>'
        arguments: '--configuration Release --no-restore --verbosity normal'

    - task: DotNetCoreCLI@2
      displayName: Publish Function Project
      inputs:
        command: publish
        arguments: '--configuration Release --no-build --output $(Build.ArtifactStagingDirectory)/publish_output'
        projects: '<path-to-your-csproj>'
        publishWebProjects: false
        modifyOutputPath: false
        zipAfterPublish: false

    - task: AzureRmWebAppDeployment@4
      displayName: 'Deploy Azure Function App'
      inputs:
        ConnectionType: 'AzureRM'
        azureSubscription: '<your-azure-subscription-name>'
        appType: 'functionApp'
        WebAppName: '<your-azure-function-app-name>'
        enableCustomDeployment: true
        DeploymentType: 'webDeploy'

Replace <your-azure-subscription-name>, <path-to-your-csproj>, and <your-azure-function-app-name> with your actual values. For general Azure Functions setup and configuration, see the Azure deployment guide.
