      I am hoping I am simply missing something so obvious I am ignoring it.
      This works:

      c=db.cscl2.aggregate([
{$bucket: {"groupBy": "$length",
           boundaries: [0,5,10,15],
    default:"other" }}
                      ]);
show(c);

      This does not: 

                                                                   
c=db.cscl2.aggregate([
{$bucket: {"groupBy": "$length",
           boundaries: {$range: [0,20,5 ]},
    default:"other" }}]);
show(c);
 "errmsg" : "The $bucket 'boundaries' field must be an array, but found type: object.",
 "code" : 40200,                                                                        
 "codeName" : "Location40200"

      So changing [0,5,10,15] to {$range: [0,20,5]} creates the error.
