Trying to read data in nodejs with mongodb which is persisted using C# with GUIDs

I have seen a few questions around this but none of them seem to directly solve the issue here.

So the scenario is there is a C# based API which writes data to a mongodb instance and uses a GUID as the _id in mongo, so for example it would look like:

"_id" : new BinData(3, "+jscvebAl0+NO0n1WySLTQ=="),

So assume that it not going to change, it will always be that data type and there is nothing I can do about it.

So in nodejs I read in a document which contains some of these UUID which relate to other resources, however when I read in the documents using the nodejs 2.0 driver the UUID vars are read in as GUID strings, like so:

"someIdField": "c1489470-4e04-49ba-ae91-a20c009254e5"

So if I were to directly use { "_id" : someIdField } it doesn't find the matching document, and I assume its because it needs to compare against the binary representation, not the string one, however I cannot seem to turn that string into something worthwhile.

I have tried using the npm uuid package to parse and then use that buffer like so:

var bytes = Uuid.parse(uuid);
return new Binary(new Buffer(bytes), 3);

However that doesnt seem to work and I have tried other solutions including base64 encoding but nothing seems to bring back results. So is there anything else I need to be doing here?
