`coder_app` breaks when `command = "..."` and `subdomain = true`

[ElioDiNino]

Version: v0.27.1+65583ec

If you create a coder_app like the following, you get a 500 error from Coder.

Either support for subdomains with commands should be added or the Terraform provider should complain that subdomain = true isn't allowed when command is set. When setting the subdomain key to false (or removing it entirely) things work fine (apart from the URL not being a subdomain).

resource "coder_app" "keeper-commander" {
  agent_id     = coder_agent.main.id
  slug         = "keeper-commander"
  display_name = "Keeper CLI"
  icon         = "https://www.keepersecurity.com/assets/branding/android-icon-192x192.png"
  command      = "keeper shell"
  subdomain    = true
  share        = "owner"
}

@ElioDiNino would you mind adding the corresponding server log with the 500 error?

[bpmct]

Thanks for reporting. We should change the Terraform provider to not support subdomain=true and command properties.

[matifali]

@bpmct and @sreya, why the command can not work when subdomain=true? Is there a technical limitation?

[matifali]

We should add a mutually exclusive condition for subdomain=true and command to ensure failure at the workspace build stage.
