Getting a googleapiclient.http warning despite file being downloaded

I'm using PyDrive2 v.1.10.0 on Mac to download google doc as docx but I keep getting the following warning even though the file gets downloaded anyway:
```
WARNING:googleapiclient.http:Encountered 403 Forbidden with reason "fileNotDownloadable"
```

Any idea how to silence that or prevent it from happening? Can someone explain why I am getting this warning?

Here is my code:
```
drive_files = drive.ListFile({'q': f"'{drive_id}' in parents and trashed=false"}).GetList()
for file in drive_files:
file.GetContentFile(file_path, mimetype='application/vnd.openxmlformats-officedocument.wordprocessingml.document')
```

_Note_: I get the same warning with `mimetype="application/pdf"` but not with `mimetype="application/zip"`

Thanks in advance!

Start at the shown GetContentFile call and compare the requests for DOCX, PDF, and ZIP mimetypes. Trace the googleapiclient.http warning for the 403 fileNotDownloadable response and determine why the download still succeeds. Done means the warning's cause and a supported way to prevent or silence it are documented or fixed.
