- A short description of the issue:
Using projects.create of Google Apps Script API, a bound script cannot be created. The API can create a bound script in Spreadsheet, Document and Form.

- A small code sample that reliably reproduces the issue. The sample should run as-is or with minimal setup, without external dependencies.

I have confirmed that this sample script can create the bound script in Spreadsheet, Document and Form. This cannot create it in only Slides.

The manually created bound script in Slides can be downloaded and updated. It cannot do only creating bound script.

# Sample script: This sample script creates a bound script in Google Docs.

function createProject() {
  var parentId = "### fileId of Slides ###";
  var res = UrlFetchApp.fetch("https://script.googleapis.com/v1/projects", {
    method: "post",
    contentType: 'application/json',
    headers: {"Authorization": "Bearer " + ScriptApp.getOAuthToken()},
    muteHttpExceptions: true,
    payload: JSON.stringify({"title": "sampleProject", "parentId": parentId})
  });
  Logger.log(res)
}

# Response
{
  "error": {
    "code": 400,
    "message": "Request contains an invalid argument.",
    "status": "INVALID_ARGUMENT"
  }
}

# appsscript.json
{
  "timeZone": "Asia/Tokyo",
  "dependencies": {

  "exceptionLogging": "STACKDRIVER",
  "oauthScopes": [
    "https://www.googleapis.com/auth/script.projects",
    "https://www.googleapis.com/auth/script.external_request"
  ]
}

In order to use above sample script, I enabled Google Apps Script API v1. And I added 2 scopes to appsscript.json (Manifests). In this installation, I have confirmed that bound script and standalone script can be created, updated and downloaded using Google Apps Script API v1. For only Slides, the bound script cannot be created. I thought that this is a bug. So I would like to report.
