I'm not sure that resource provider is the current Terraform supported one. The Terraform HashiCorp docs point to this:

All the information is listed here for the site_config variables: https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/linux_function_app

"A site_config block supports the following:

• always_on - (Optional) If this Linux Web App is Always On enabled. Defaults to false."

Using this provider instead:

resource "azurerm_linux_function_app"

Here's an example site_config:

  site_config {
    always_on			= "true"
    ftps_state          = "Disabled"
    http2_enabled       = true
    minimum_tls_version = "1.2"

    application_stack {
      dotnet_version              = "8.0"
    }
}

Hopefully that will then solve the issue. If it does, please mark this as the accepted answer.
