  }
}

Debug Output/Panic Output

No panic

Expected Behaviour

1. 64 Bit platform is configured for the function, because use_32_bit_worker = false when using powershell_core_version = "7" or powershell_core_version = "7.2"
2. PowerShell Core Version is set to expected version 7 or 7.2

Actual Behaviour

1. 32 Bit platform is configured for the function. It looks like the platform is not set at all.
2. PowerShell Core Version is empty

Steps to Reproduce

1. terraform init
2. terraform apply

The workaround for setting 64 Bit is to use app_settings = { FUNCTIONS_WORKER_RUNTIME = "powershell" }

instead of application_stack { powershell_core_version = "7.2" }

but that still keeps the PowerShell Core Version empty

@kpakur The powershell version is not being set correctly, I will submit a pr to fix it.

Has any progress been made with this PR? We are seeing the same thing where the PowerShell Core version is not being populated by configuring the application_stack settings. This is also occurring with azurerm_windows_web_app and azurerm_windows_web_app_slot and the same issue exists when trying to configure .NET and its version through the application_stack block.

application_stack {
  current_stack  = "dotnet"
  dotnet_version =  "v6.0"
}

Using the above application stack settings results in neither the stack or version fields being populated.

has there been any update on this bug? We are also experiencing PowerShell Core version setting value is not being acknowledged.

@amira1o-edf my understanding is that this has been fixed as of v3.39.0 of the azurerm provider: https://github.com/hashicorp/terraform-provider-azurerm/pull/19685

[rcskosir]

Thanks for taking the time to submit this issue. It looks like this has been resolved as of #19685. As such, I am going to mark this issue as closed.
