docs: // GetFileUploadURL API operation for Amazon Mechanical Turk.
  //
  // The GetFileUploadURL operation generates and returns a temporary URL. You
  // use the temporary URL to retrieve a file uploaded by a Worker as an answer
  // to a FileUploadAnswer question for a HIT. The temporary URL is generated
  // the instant the GetFileUploadURL operation is called, and is valid for 60
  // seconds. You can get a temporary file upload URL any time until the HIT is
  // disposed. After the HIT is disposed, any uploaded files are deleted, and
  // cannot be retrieved. Pending Deprecation on December 12, 2017. The Answer
  // Specification structure will no longer support the FileUploadAnswer element
  // to be used for the QuestionForm data structure. Instead, we recommend that
  // Requesters who want to create HITs asking Workers to upload files to use
  // Amazon S3.
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for Amazon Mechanical Turk's
  // API operation GetFileUploadURL for usage and error information.

  // Returned Error Codes:

  //   Amazon Mechanical Turk is temporarily unable to process your request. Try
  //   your call again.
  //
  //   * ErrCodeRequestError "RequestError"
