java.lang.NullPointerException (CcedkWrapper.java:842)

I was able to replicate a problem that Kiara started getting yesterday. Here's the stack trace from the console log:

Note: RPC client IP has been obsfucated.

I've confirmed that there were no changes between the previous run that worked and this run to the parameters passed in through options.json.

CCEDK "upgraded" their back-end recently, so I'm hoping that this is just a matter of a change in their API vs. something deeper.
