Hi,
I am trying to run the following mapreduce query across my cluster:

[]}", "keep":true}}]}'
{"lineno":466,"message":"SyntaxError: syntax error","source":"()"}
Have you tried executing your javascript outside of Riak?
ie. paste the function into the Chrome debugger, then call it with a
Riak-like data structure.
Also, consider wrapping the code in your function with an eval so you
can catch errors that occur. (Then either ejslog them or return them as
results of the map phase)
