Sandbox: Get the score for a previous submission GET /submissions/{id}/score

[bin...@athenahealth.com]

We are trying to test score retrieval for previous submissions in the sandbox but receive errors like the following:

{
  "error": {
    "type": "NotFoundError",
    "message": "No submission found for id: 00000000-0000-0000-0000-000000000000"
  }
}

Is there a valid submission id that can be used for testing?

I was able to query all submissions in the sandbox and then use 1 of the returned submission ids.
