ModuleNotFoundError

[chozelinek]

I'm using Python 3.7
I'm trying to list the files of a directory using the method Use Service account.
I'm getting an error with a traceback which does not break the code (I get the list of files) but it is a bit annoying.

I did a bit of research and making a small modification I got it working without the error. I'm making a PR so you can check and test it.

resource = {
...         "service_account": get_credentials(),
...         "id": parent_folder_id,
...         "fields": "files(name,id,mimeType)",
...     }
res = getfilelist.GetFileList(resource)
