Typescript model export not working

[fabiante]

Hi,

I can't export my model as my model type. This line gives me this error:

src/model/person.model.ts(19,14): error TS2322: Type 'Model<TUserModel>' is not assignable to type 'TUserModel'.
  Type 'Model<TUserModel>' is not assignable to type 'Document'.
    Property 'increment' is missing in type 'Model<TUserModel>'.
