红宝石 | badRequest：不支持请求的转换。 (谷歌::Apis::ClientError) |导出文件时

Question

我对 export_file 方法有一些问题。它似乎不时工作 这是我的完整代码

OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'
SCOPE = 'https://www.googleapis.com/auth/drive'
CLIENT_SECRETS_PATH = 'private/credentials-2.json'
TOKEN_PATH = 'private/tokens.yaml'
USER_ID = ENV['USER']

class GoogleDriveGetFiles

  def call(file_name)
    @file_name = file_name
    credentials = auth
    drive_service = drive_service_auth(credentials)
    file_id = get_file(drive_service)
    write_in_file(file_id, drive_service)
  end

  private

  def auth
    client_id = Google::Auth::ClientId.from_file(CLIENT_SECRETS_PATH)
    token_store = Google::Auth::Stores::FileTokenStore.new(file: TOKEN_PATH)
    authorizer = Google::Auth::UserAuthorizer.new(client_id, SCOPE, token_store)
    credentials = authorizer.get_credentials(USER_ID)
    if credentials.nil?
      url = authorizer.get_authorization_url(base_url: OOB_URI)
      puts "Open #{url} in your browser and enter the resulting code:"
      code = gets.chomp
      credentials = authorizer.get_and_store_credentials_from_code(
        user_id: USER_ID, code: code, base_url: OOB_URI)
      end
      
      credentials
  end
    
  def drive_service_auth(credentials)
    drive_service = Google::Apis::DriveV3::DriveService.new
    drive_service.authorization = credentials
    
    drive_service
  end
    
  def get_file(drive_service)
    files = drive_service.list_files(fields: 'nextPageToken, files(id, name, mimeType)').files
    
    file_id = nil
    files.each do |file|
      if file.name == @file_name
        file_id = file.id
        puts file.name
        break
      end
    end
    file_id
  end

  def write_in_file(file_id, drive_service)
    # binding.pry
    file = drive_service.get_file(file_id)
    File.write("output/#{@file_name}.txt", drive_service.export_file(file_id, 'text/plain'))
    puts 'Succefully write in file'
  end

end

get_file 方法工作正常，但 export_file 不工作

我试过调试库但无法查明错误的确切原因。非常感谢任何有关如何解决此问题的帮助或建议！

我工作到晚上 7:30，现在我有错误。 这是我的错误堆栈跟踪。
