I created a fresh Coder deployment, added the docker-code-server template, and my code-server app is stuck in the Initializing... state.

The resource is configured as such:

resource "coder_app" "code-server" {
  agent_id     = coder_agent.main.id
  slug         = "code-server"
  display_name = "code-server"
  url          = "http://localhost:8080/?folder=/home/coder"
  icon         = "/icon/code.svg"
  subdomain    = false
  share        = "owner"

  healthcheck {
    url       = "http://localhost:8080/healthz"
    interval  = 3
    threshold = 10
  }
}

But, when I curl the health check endpoint within the workspace, it reports 200:

coder@test-1:~$ curl -v 127.0.0.1:8080/healthz
*   Trying 127.0.0.1:8080...

I found this in /tmp/coder-agent.log:
