Unknown Error completing Challenges

Koryphaia

This is the first time this has happened. I am doing the daily challenges (today's is training droids against boba fett) and once I complete the challenge instead of getting my rewards I am getting: "An unknown error occurred". However it still burned through my 3 daily challenges. Anyone else run into this?
