We use a python client api to download files from google drive and periodically, some files cannot be downloaded, although the listing of all files indicates that the owner of the file is the user whose authorization data we use.

The api handle that call client is /{file_id}/export.

In this case, the error that occurs is enoughFilePermissions, which is a file modification error: #insufficient-file-permissions

The problem only affects two types of files: application/vnd.openxmlformats-officedocument.wordprocessingml.document. However, other files download successfully.

And most importantly, the problem occurs periodically on some files, that is, usually the files are downloaded successfully
