Changed typeof err

[hex7c0]

Hi guys,
with version 3.9.7 (unstable), unlike since <= 3.9.6
errargument, on callback function, is changed from null to undefined
is that correct?

What function are you passing a callback to that you get this issue?

hi Valeri
here is the snippet

// 3.9.7
mongo.model
        .where(where)
        .sort('species')
        .select(selected)
        .find(function(err, found) {

          console.log(where) // {}
          console.log(selected) // species name
          console.log(err) // undefined
          if (err !== null) {
            debug(err.message);
          }
});

// 3.9.6
mongo.model
        .where(where)
        .sort('species')
        .select(selected)
        .find(function(err, found) {

          console.log(where) // {}
          console.log(selected) // species name
          console.log(err) // null
          if (err !== null) {
            debug(err.message);
          }
});

Yeah I think this may be related to some work done to add hooks for find. From what I've seen it's more idiomatic to return null instead of undefined in callback errors. I'll fix this. Thanks for your feedback :)
