Any suggestions?

Are you getting this when you are enabling a projection?

Yes, I believe so.
We have over 3500 tests and our projection create, enable tests did fail on some builds. But I will have to do some more analysis to be 100% sure.

I do believe there is a card up for this. The resolution would be to guard against performing actions on a projection that is in the process of transitioning. In the interim, you could query the projection to make sure it’s stopped before you start them.

Thanks! we will do just that
