Error: cursor id <id> not found

What is the current behavior?
In latest mongoose ( I tested 5.7.4 and 5.7.5) in my tests I see Error: cursor id 9058772029368767025 not found error. When I downgrade to 5.7.1 everything is ok.

What is the expected behavior?
In 5.7.5 my tests doesn't fail

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
node: v10.16.1
mongodb: 4.2

Can you please provide the code that is failing and a stack trace? Without that it's hard for me to guess what the issue might be.

I'm seeing the same issue on 5.7.5. Query looks like:

model
  .find(options)
  .read('sp')
  .batchSize(1000)
  .cursor()
  .eachAsync(func, { parallel: 100 })

And I'm seeing two variations of the error:

@vkarpov15 Seems very much related to #8235

[vkarpov15]

@AndrewBarba is right, this looks like a duplicate of #8235. Should be fixed in 5.7.6
