Model buffering takes more than 10000ms for `findOne` operation

Do you want to request a feature or report a bug?

Possibly a bug.

What is the current behavior?

Buffering takes more than 10000ms and this has an impact on app usage. The error message is Operation wallets.findOne() buffering timed out after 10000ms. This error is intermittent (i.e it comes and goes).

This error message is due to Mongoose thinking it isn’t connected to the database. You can prevent Mongoose from throwing this error by disabling buffering: mongoose.set('bufferCommands', false), see https://mongoosejs.com/docs/guide.html#bufferCommands. However, if the issue is due to issues connecting to MongoDB, you’ll just get a ServerSelectionError instead of a BufferTimeoutError.

My recommendation is to disable buffering and see if that helps. If it does, then this is a Mongoose bug and I’ll need some more information to track it down.

@henrispkl please make sure you carefully review our docs on testing with Jest: https://mongoosejs.com/docs/jest.html . Jest is filled with unpredictable footguns, and your code makes it seem like you’re running into one of them: setting up your Mongoose connecting in globalSetup

I have the same issue, on my local machine works but not on the server. The Mongodb on server has been used by express, but when I run a node script to manage the database directly gives me this error.

It connects, but when I try to do a .find() it gives me the buffer error… Did try everything proposed here with no sucess…

is any previous version working? tested a lot under 5.X but same behaviour, works local but not when runs in the server

Update:

What i’ve found here, if I import the Model from another file/folder, it gives me error!

Solution

I’ve found my problem!!! I had a left over node_modules inside on of the projects folder. So, if u have a similar issue, check if u have just ONE node_modules over your folders!
