@ypanyukov there was a bug introduced in bson 1.0.2 on January 2, which was fixed a couple of hours ago in 1.0.3 https://github.com/mongodb/js-bson/commit/35f5264446fb74e475ecf25f94ce7b177b5b35fd

Chances are you have bson 1.0.2 installed now (verify with npm list bson).

Re-intstall all deps, verify that bson is 1.0.3 and see if it works now.

Is it possible that this can be made a requirement for mongoose (^1.0.3)? This was a really hard issue to come by and fix - it would be nice to have it magically taken care of with a mongoose upgrade.

@harangue updating to the latest mongo and mongoose had this "magically taken care of" :)

Tbh the best solution would just be to deprecate bson 1.0.2 . mongoose needs to have the same package.json entry for bson as mongodb-core to avoid potential conflicts
