Answer 1

Per mongoose docs: https://mongoosejs.com/docs/faq.html

Q. I'm using an arrow function for a virtual, middleware, getter/setter, or method and the value of this is wrong.

A. Arrow functions handle the this keyword much differently than conventional functions. Mongoose getters/setters depend on this to give you access to the document that you're writing to, but this functionality does not work with arrow functions. Do not use arrow functions for mongoose getters/setters unless do not intend to access the document in the getter/setter.
