Currently, if you start a new deploy right after tearing down a previous one, you can hit the following error:

Configuration has 2 errors, fix them before proceeding. Ignoring these errors is likely to lead to a failed deploy.
It goes away after a minute or two. I think we should retry our workflows instead of making a user retry.
