Hi!

I'm trying to run custom erlang-written map/reduce and get this error:

There was an error in processing a map or reduce function :
<html><head><title>500 Internal Server
Error</title></head><body><h1>Internal Server Error</h1>The server
encountered an error while processing this request:<br><pre>
{error,{error,function_clause,
              [{chashbin,itr_value,
                         [done],
                         [{file,"src/chashbin.erl"},{line,138}]},
               {chashbin,itr_next_while,2,
                         [{file,"src/chashbin.erl"},{line,182}]},
               {riak_core_apl,first_up,2,
                              [{file,"src/riak_core_apl.erl"},{line,139}]},
               {riak_kv_mrc_pipe,random_constant_hash,0,
                                 [{file,"src/riak_kv_mrc_pipe.erl"},
                                  {line,1060}]},

               {riak_kv_mrc_pipe,mapred_stream,2,
                                 [{file,"src/riak_kv_mrc_pipe.erl"},

               {riak_kv_wm_mapred,pipe_mapred,2,
                                  [{file,"src/riak_kv_wm_mapred.erl"},

{line,163}]}]}}</pre><P><HR><ADDRESS>mochiweb+webmachine web

Please point me how do I investigate what's wrong.

Thank you!
