}

Debug Output/Panic Output

Planning failed. Terraform encountered an error while generating this plan.
╷
│ Error: expected site_config.0.application_stack.0.powershell_core_version to be one of ["7" "7.2"], got 7.4
│ 
│   with module.functionapp.azurerm_windows_function_app.example,
│   on functionapp/main.tf line 55, in resource "azurerm_windows_function_app" "example":
│   55:             powershell_core_version            = "7.4"

Expected Behaviour

The function app should be deployed with powershell 7.4 as powershell 7.2 will be deprecated on 08/11/2024

Actual Behaviour

The function app can only be deployed with powershell 7.2 (powershell 7 has already been deprecated)

Steps to Reproduce

Standard terraform plan/deploy.
