Configuration is not working; json: unknown field

[Niklas Karoly]

Describe the bug

Compiling the project from source and running it with a config that points to a configserver fails with the following error:

{"timestamp":"2022-09-18T18:19:44Z","level":"error","code":"SSH_BACKEND_REJECTED_HANDSHAKE","message":"The backend has rejected the user after successful authentication. (failed to load connections-specific configuration (Configuration request to backend failed, giving up (Failed to decode HTTP response (json: unknown field \"container\"))))","details":{"connectionId":"id","module":"ssh","remoteAddr":"my_ip"}}

The config response looks something like this:

"config": {
  "backend": "docker",
  "docker": {
    "execution": {
      "disableAgent": true,
      "idleCommand": [
        "/bin/sh",
        "-c",
        "sleep infinity & PID=$!; trap \\\"kill $PID\\\" INT TERM; wait"
      ],
      "container": {
        "image": "some_image"
      }
    }
  }
}

To Reproduce

Simply compile the latest commit and provide a config similar to mine, it should fail. 0.4.1 works with the same response.

Expected behavior

It should spawn a container with the provided image.

Version

0.5.0

Thanks! :)
