Node mongodb: Error: connection closed due to parseError
Answering my own question to hopefully stop the next person from tearing their hair out:
As noted here, this error message is useless and doesn't relate to the actual problem. The production Mongo driver throws away all errors in a catch block.
To find what the error actually is:
open your
node_modules/mongodbfind
server.jslook for
mongoReply.parseBodylog the
errto see something actually useful.
In my case:
ReferenceError: collection is not definedEdit: Node MongoDB native 1.4 is now stable, and includes a fix to this bug.
For people who are using mongoose instead mongodb can check in the following location for the same.
/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection
