Here is the offending line (20):

node-object-hash/objectSorter.js

Lines 15 to 21 in 0ac4d88

function _guessObjectType(obj) {
if (obj === null) {
return 'null';
}
switch (obj.constructor.name) {
case 'Array':

This assumes that every (non-null) object has as constructor property, which is not generally the case.
