Issue with Google Drive Connector Full Refresh

[benjaminwilen]

Hey Team,
I'm running into an issue triggering a full-refresh sync using the Google Drive connector as the source. The initial sync works as expected, but subsequent syncs return 0 records. The logs show that there is a connection state being stored in between runs, which is in my experience unexpected for full-refresh syncs and I'm assuming the root cause behind the issue. If anyone can provide support that would be greatly appreciated!

More context:
In file_based_source.py, streams() seems to have the logic to determine whether a sync should be incremental or a full-refresh. However, the conditional requires

                if (
                    sync_mode == SyncMode.full_refresh
                    and hasattr(self, "_concurrency_level")
                    and self._concurrency_level is not None
                ):

which seems like it might be the cause behind the issue, considering the Google Drive connector doesn't override self._concurrency_level.
