Occasionally (2 out of 5 times for me) a model.DoesNotExist error will be thrown on (at least) ObjectTag sink.

It's likely that we're getting to the Celery task before the MySQL transaction is committed in Studio. We should look at all of the tag models and see if any others might be prone to this. We have this pattern for working around the issue, and should get that fix in ASAP: https://github.com/openedx/platform-plugin-aspects/blob/e3fea7cf01767a51fcc6f57b8b29b1b63b5dcb91/platform_plugin_aspects/signals.py#L83
