AzureFunctionApp@1 has a bug in appSettings parsing

[Yevhen-Mordak]

Required Information

The task AzureFunctionApp@1 has a bug in appSettings argument parsing. The trailing space is required after each line in appSettings for proper parsing.

Type: Bug
Task Name: AzureFunctionApp@1

Environment

• Server - Azure Pipelines
• Agent - Hosted

Issue Description

the all marked trailing spaces are mandatory.

Desired fix: new line is enough and trailing spaces have zero influence on how appSettings are parsed.

Hello Yevhen,

Its not trailing spaces. app settings is considered as single string and we need spaces between two settings. it is documented on official task doc: https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/deploy/azure-function-app?view=azure-devops#arguments

I know spaces are required. I just raise I'm the second person in a team who spent hours to figure out that.

Can you please add '\n' as a valid separator same as the space? that would be great

Issue has been fixed and it will take 30 to 45 days to deploy the fix in production.

Hi,

I'm facing the same issue here. To work, I need to put a whitespace at the end of each pair. For anyone facing the same issue, I created a PowerShell script as a workaround.

- task: PowerShell@2
  displayName: 'Parsing secrets'
  inputs:
    targetType: 'inline'
    script: |
      $blob_storage_function = $env:blob_storage_function
      $api_host_url= $env:api_host_url

      $appsettings = "-AzureWebJobsStorage `"$blob_storage_function`" "
      $appsettings += "-ApiUrl `"$api_host_url`" "

      Write-Host "##vso[task.setvariable variable=APPSETTINGS_VALUE]$appsettings"

- task: AzureFunctionApp@1
  displayName: Publish Azure Function
  inputs:
    azureSubscription: "service connection"
    appType: 'functionApp'
    appName: 'app-name'
    package: '$(ArtifactPath)'
    resourceGroupName: "rg-resource-group"
    deploymentMethod: 'auto'
    appSettings: "$(APPSETTINGS_VALUE)"
