我必须开发一个脚本，该脚本每次在特定目录中创建一个文件时，都应在必须返回一些数据的特定API的主体调用中使用此文件。 为了监视目录，我正在使用看门狗python库，该库采用已创建文件的路径并调用指定用于调用api的另一种方法，并将文件路径传递给该方法。 这些是上传文件的api的主要规则： api rules for upload file

这些是我写的脚本： 第一个用于看门狗，第二个用于调用api

    path_file_created = event.src_path

    print(type(path_file_created))
    #file_created = open(path_file_created,'rb')
    file_created = path_file_created

这是我收到的回复：

尤其是我不明白为什么会返回此类错误：

{'status': 'KO','error': "TypeError: Cannot read property 'originalname' of undefined"}
