I think you're using an older version of json11 (the line numbers in your error message don't match up with the latest master). The issue you mentioned was already fixed in alternative way using the NullStruct helper: https://github.com/dropbox/json11/blob/master/json11.cpp#L220
If you pull the latest you should be all set.
