I am trying to download a random file from a Google Drive using Google Drive API. Although after running the code I got an error message: The user has not granted the app (app_code) read access to the file (filename). How can I grant a read access to the file? I haven't found anything on the internet, and in the API Dashboard either.

 # Call the Drive v3 API

    results = service.files().list(

        pageSize=1000, fields="nextPageToken, files(id, name)").execute()

    items = results.get('files', )

    rand_item = random.choice(items)

    print('{0} ({1})'.format(rand_item['name'], rand_item['id']))

    if not items:

        print('No files found.')

    else:

        request = service.files().get_media(fileId=rand_item['id'])

        fh = io.BytesIO()

        downloader = MediaIoBaseDownload(fh, request)

        done = False

        while done is False:

            status, done = downloader.next_chunk()

            print("Download %d%%." % int(status.progress() * 100))

Its due to the scope. You only gave metadata.readonly access

Change it to
'https://www.googleapis.com/auth/drive.readonly'
