Thx @mikethompson !

My default-value for app-db includes {:date-moved-out (js/Date.). I have a handler and a subscription defined, but my console warns me re-frame: no subscription handler registered for: ":date-moved-out". Returning a nil subscription..

Is there something about the value that is causing this error? The handler and subscription look like all my other handlers and subscriptions.

Nothing about that name or value should cause a problem
