This PS resolves a recent issue with Deckhand in which missing
substitution sources cause Promenade to fail during genesis,
while using Deckhand to render documents. The fix involves
introducing a new flag called fail_on_missing_sub_src which
if False logs a warning rather than raises an exception
in the event that a substitution source document is missing.
Also adds better exception handling and logging around
Deckhand.
Example error:
