AssertionError: expected { Object (_bitField, _fulfillmentHandler0, ...) } to have a property 'length'

[ashishagarwal1686]

I am getting assertion error.
my code is like this :

return expect(User.find({}).exec()).to
.have.length(0);

Don't know where the mistake is. Can anyone help me out with such problem.

@ashishagarwal1686 Using .length as a method assertion is deprecated because of issues related to functions having a .length property that's immutable in older engines. Please try .lengthOf in its place.
