Node mongodb: Error: connection closed due to parseError
mongodb, node-mongodb-native, node.js
Solution
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/mongodb`
find `server.js`
look for `mongoReply.parseBody`
log the `err` to see something actually useful.
In my case:
ReferenceError: collection is not defined
Edit: Node MongoDB native 1.4 is now stable, and includes a fix to this bug.
Problem
Using the native 'mongodb' npm package, I'm receiving ``` Error: connection closed due to parseError ``` When making a very basic query: ``` collections.myCollection.findOne({id: someID}, function (err, repo) { ... }) ``` The weird thing is, the exact same query has run before. Types are identical for each query, etc.
