"bad_type" error when trying to create mnesia tables

For the life of me, can't figure this out. I'm trying to create mnesia tables, but keep getting this weird error.

Here is my command:

ok = mnesia:create_schema(Nodes),
rpc:multicall(Nodes, application, start, [mnesia]),
{_, ok} = mnesia:create_table(rr_events,
        [{attributes, record_info(fields, rr_events)},
         {index, [#rr_events.key]},
         {disc_copies, Nodes}]),
rpc:multicall(Nodes, application, stop, [mnesia]).

Here is my record:

-record(rr_events, {key, events=[]}).

Here is the error:

=PROGRESS REPORT==== 24-Mar-2016::21:53:42 ===
         application: mnesia
          started_at: nonode@nohost
** exception error: no match of right hand side value
                    {aborted,{bad_type,rr_events,{index,[2]}}}
     in function  rr:install/1 (c:/Users/zzzz/Projects/zzz/zzz/rr/rr/_build/default/lib/rr/src/rr.erl, line 13)

Any idea what this might be? Cannot figure this out.
