Collection.find_one_or_404 hides stack trace

[Joe-Heffer-Shef]

Hi,

When I try to retrieve a single item from a MongoDB collection and it isn't present, I want an error to be raised, which is the purpose of Collection.find_one_or_404. However, a 404 screen is shown which prevents me from seeing a stack trace (in Flask debug mode.)

Please could find_one_or_404 instead raise some kind of not-found exception, rather than using flask.abort. This way, I could see the stack trace (or handle the error appropriately using Flask error handlers.)
