Issue Description

With no deployment type defined in AzureFunctionApp@2 inputs the task throws an error.

  - task: AzureFunctionApp@2
    inputs:
      azureSubscription: prod
      runtimeStack: "NODE|20"
      appType: functionAppLinux
      appName: "app1"
      package: $(System.DefaultWorkingDirectory)/build$(Build.BuildId).zip

Results in The Deployment Type option does not apply for Linux Consumption.

Reverting to the same configuration on v1 works fine.

@jamie-oconnell can you let me know which SKU you are deploying too? Linux Consumption, Linux Dedicated or Flex Consumption?

[jamie-oconnell]

Linux consumption.

[scottrudy]

I'm also using Linux consumption and see this with auto and runFromPackage. My runtime stack is DOTNET-ISOLATED|9.0. I switched back to AzureFunctionApp@1 and no message.

[FinVamp1]

Can I just confirm if the deployment fails after this error or if it continues without a failure?
The error message is designed to just mention that the deployment type variable

  "options": {
    "auto": "Auto-detect",
    "zipDeploy": "Zip Deploy",
    "runFromPackage": "Zip Deploy with Run From Package"
  },

Will not be used for deploying to Linux Consumption.

I think we can update or remove that message to avoid confusion but I want to ensure that we aren't failing deployments.

[scottrudy]

I am not experiencing any failure, just confusion on the message as you mentioned.

I am seeing this with a Linux Flex Consumption Function App as of today, 5/9/2025. The package still deploys thankfully.
