Phase errors getting swallowed

[david-boles]

@nkumar15-brown-university errors in my AnalyzePhase's write method are getting swallowed; it made it really tricky to debug. Should that method have its own error boundary? If an error occurs, should it still publish (like it does currently if not in position mode)?

To clarify, it's not just that the errors aren't helpful, its that if an error occurs there's no indication of it.
