Hello list, I am using Riak 2.0.0rc1 and nlf’s riakpbc <https://github.com/nlf/riakpbc/> client. While performing a map reduce operation with the request input: inputs: ['test1', 'mapred_test’] where ‘test1’ is the bucket type and executing the ‘Riak.mapValuesJson’ function, I am getting the following error:
{ [Error: Error processing stream message:

Other operations like listing keys and contents work fine. For example, the
value of key '44dd14d4-8d53-460d-8e64-258d375d65fc’ (uuid4) is:
{ context: <Buffer 83 6c 00 00 00 01 68 02 6d 00 00 00 08 23 09 fe f9 53 ea 22
e3 61 01 6a>,
type: 3,
value:
{ map_value:
[ { field: { name: 'volume', type: 3 },
register_value: '2325100' },
{ field: { name: 'open', type: 3 }, register_value: '514.43' },
{ field: { name: 'low', type: 3 }, register_value: '511.40' },
{ field: { name: 'high', type: 3 }, register_value: '517.45' },
{ field: { name: 'date', type: 3 },
register_value: '2007-08-27' },
{ field: { name: 'close', type: 3 }, register_value: '513.26' },
{ field: { name: 'adjusted close', type: 3 },
register_value: '513.26' } ] } }
The code for the nodejs script and python script for populating the db:

Any help ?
