I am trying to pass surveyMetadataIds in the export-responses API, but keep running into an error.
Here is the body of my request:
{  
  "format": "csv",
  "breakoutSets": false,
  "compress": true,
  "exportResponsesInProgress": false,
  "formatDecimalAsComma": "false",
  "includeDisplayOrder": "false",
  "limit": 6000,
  "multiselectSeenUnansweredRecode": -2147483648,
  "seenUnansweredRecode": -2147483648,
  "timeZone": "America/Denver",
  "useLabels": true,
  "allowContinuation": false,
  "includeLabelColumns": false,
  "startDate": "2020-12-01T21:21:29.373507400Z",
  "surveyMetadataIds": [
    "\\finished\\" 1"
  ]  
}
Here is the error I get: 
"errorCode": "RTE_2",
   "errorMessage": "The following invalid columns were requested: [\\finished\\" 1]"
Based on the information in this link, I believe I am passing this correctly, but I must be missing something.
