Typescript Error at `pre` hook?

I have i am trying to implement pre hook. The following code works fine, but it is giving me TS lint error potantially invalid reference access to a class field via this. of a nested function.

@pre<Cat>('save', function (next) {
  this.updatedAt = new Date();
  next();
})

But the above code working though. It updates my updatedaAt field.

I am not sure this is related to this library or typegoose itself. But any help would be appriciated!

Thanks.

@emjimadhu @AlecDusheck @kpfromer I use webstorm and this is what I use

@pre<User>('save', async function(this: DocumentType<User>, next) {})

Yeah I think something about the decorator confuses the WebStorm inspector and makes it believe that you don’t have access to this
