Mongoose / MongoDB error (related to replica set maybe)?

[krstffr]

Just installed glimpse and tried running it in a very simple application, which basically does a .find on some Mongoose model, and it throws the error below.

Update when looking deeper into this: This only occurs when I connect to a replica set hosted on MongoDB Atlas though, not when running a single mogod on my own computer.

Versions Mongoose: 4.9.9 Express: 4.15.2 Node: 6.10.3

We apologize for the bug you've found, and thank you for the error report!

We'll get this fixed and a patch release out as soon as possible.

To aide in our efforts to reproduce this, can you verify the version of the mongodb package installed by Mongoose for us?

Thanks for reporting this @krstffr. Any chance you can get us a small project that reproduces the issue? I'll take a quick look at our logic. I thought our mongo DB instrumentation was turned off at the moment...

[krstffr]

Hi @mike-kaufman, the problem though is that it works when using my local DB, but not when I'm using the MongoDB Atlas one, so I might be able to set up this testv app for you if you yourselves are willing to set up an Atlas DB account etc since I unfortunately can't lend you mine?

[mike-kaufman]

Thanks @krstffr. I'll see if I can set up an atlas DB & repro this...

[krstffr]

Cool @mike-kaufman, thanks a lot!

Got the same error too with compose.io (db got replica) using https://github.com/Automattic/monk.
