Stack trace is printed when some exception is thrown on scaladex #623

Open oswaldo opened 4 years ago

oswaldo commented 4 years ago

Just saw an exception that happened for a few minutes and now is ok again.

Still, I'm writing this as a suggestion that maybe there should be some nice looking 500 "we are working on it" page instead of the output I got below clicking on any artifact link:

Thank you @oswaldo for reporting this issue. A nice looking Error 500 page would be very nice to have!
