Hello MongoDB Community
I am having trouble with $not operator. Getting error that "$not cannot have a regex". I looked into official documentation but it's says it shall work from version 4.0.7. So, I tried updating my mongodb and installed latest stable version 4.0.10. But still getting same error. I am attaching my error screenshot. Please let me know if I am doing anything wrong.
Many thanks in advance.
