Drive API request not showing any files from Google Drive

I’m working on a desktop app to fetch files from my Google Drive. Here’s what I’ve done:

def get_drive_service():
    creds = load_credentials('drive_token.json')
    if not creds or creds.expired:
        creds = refresh_credentials()
    return build('drive', 'v2', credentials=creds)

def fetch_drive_files(service):
    params = {}
    if next_page:
        params['pageToken'] = next_page
    result = service.files().list(**params).execute()
    print(result)

drive_service = get_drive_service()
fetch_drive_files(drive_service)

I’ve set up authentication and it works fine. But when I try to list the files, the result shows an empty list. Any ideas why this might be happening? Has anyone run into this issue before?

Have you considered using the ‘fields’ parameter in your API request? This can help specify exactly what data you want to retrieve, potentially solving issues with empty results. For example:

result = service.files().list(fields=‘nextPageToken, items(id, title)’).execute()

This fetches only the file IDs and titles. It’s also worth checking your app’s permissions in the Google Cloud Console. Ensure you’ve enabled the Drive API and that your OAuth consent screen is properly configured. If you’re using a service account, double-check that the target files are explicitly shared with its email address.

Lastly, consider upgrading to the v3 API. It offers improved performance and more intuitive methods for file retrieval. The transition might resolve your current issue and provide a more robust solution moving forward.

hey sophia, i had this problem too. check if ur using the right API version. v2 is old, try v3. also, make sure u have the right scopes. sometimes the default ones dont work. oh and double check ur not using a empty google account by mistake lol. hope this helps!

I experienced a similar situation when my Google Drive integration returned no files despite successful authentication. In my case, the problem was related to the OAuth scopes; I had to check that I was using the correct ones (for example, https://www.googleapis.com/auth/drive.readonly or https://www.googleapis.com/auth/drive) to allow file retrieval. I also made sure I was using the intended account because it’s easy to inadvertently sign in with a different one lacking files. Additionally, I experimented with filtering the request by specifying a particular mime type, which helped narrow down the search results. If you are using a service account, verify that the necessary files are shared with the account’s email. Finally, I migrated to the v3 API, and it resolved some unexpected behaviors. Checking the API logs in the Google Cloud Console can provide further insights if the issue persists.
