I am stuck at step 5 of automation superbadge:  new Opportunity with a 'Prospecting' stage for a 'Prospect' Account did not successfully create a Task for the Account owner with the Subject 'Send Marketing Materials'. I am checking for nullvalues in trigger and set up correct fields I guess. Hard to figure out what the problem is as the screen error is very generic. BTW I am 1 week new to SF, but manage to clear hurdles till now. I am spinning my wheels for 2 days now with this problem. Any help much appreciated !
