Error
If the server returns an empty string, BaseUpdater.versions will be set to None and thus trying to get the update status will fail:
TypeError: argument of type 'NoneType' is not iterable File "nxdrive\engine\workers.py", line 171, in run File "nxdrive\engine\workers.py", line 252, in _execute File "nxdrive\updater\base.py", line 334, in _poll File "nxdrive\updater\base.py", line 214, in _get_update_status File "nxdrive\updater\utils.py", line 105, in get_update_status
In fact, to reproduce:
>>> import yaml >>> yaml.safe_load("") >>> versions = yaml.safe_load("") >>> versions is None True
Sentry Issue: NUXEO-DRIVE-186
Fix
Enforce versions to be an empty dict in BaseUpdater._fetch_versions().
