You're seeing this error because you have DEBUG = True in your
Django settings file. Change that to False, and Django will
display a standard page generated by the handler for this status code.

@NeilAllavarpu I know why this isn't working. It's the same bug we saw on your local machine when we met up in-person. None of these courses have hourly tuition so we can't generate a price quote which depends on hourly tuition.

@jerrylinew Perhaps for a later point, but we'll need to discuss with Maggie how to handle this.

[dhuangg]

closing this issue for now, until @jerrylinew and I can discuss how to handle this
