Exceptions raised by actions are getting lost

Play Framework

This is the exception that I get instead. My play project is part of a multi-project build, and I’m running it with sbt api/run. I don’t have any special error handling installed. Is this a Play problem or an SBT problem?

[info] p.c.s.AkkaHttpServer - Listening for HTTP on /[0:0:0:0:0:0:0:0]:9000

(Server started, use Enter to stop and go back to the console...)
