CloudKit Dashboard goes blank when making a query

I have two Core Data entities synching with CloudKit nicely. When I query records for one in the Dashboard, the results are displayed as expected. However, when I query records for the other entity, the Dashboard goes black (completely, I mean, no navigation, etc.). I can confirm that changes to the records are synching across devices. I just can't figure out what is making the Dashboard query fail. Has anyone else encountered the same issue? Was there a solution? (BTW, I have made recordName queryable, since I've had that problem in the past. Also, my app is in development - not production.)

If you're still having this issue, please take a look at your javascript console for errors, or even a request UUID. That can be helpful in figuring out what is going wrong during the query. There are not any scenarios where the dashboard should go blank.

There could have been a transient issue with the dashboard or back-end server, but I did not see anything in our logs around that timeframe.
