Typegoose not working with vuetify in electron

Question

Im trying to build a very simple model with typegoose inside Vue + electron.

This is my simplified code:

import { getModelForClass, prop, modelOptions } from '@typegoose/typegoose';

@modelOptions({ 
                schemaOptions: { collection: 'ability_group' }
              })
export class RmfCategoryGroup2 {

  @prop( {type: () => String} )
  public name: string;
}

export const CategoryGroup2DAO = getModelForClass(RmfCategoryGroup2);

When app launches in electron, the window opens and i have an error:

Uncaught TypeError: Right-hand side of 'instanceof' is not an object
    at addModelToTypegoose (typegoose.ts:180)
    at getModelForClass (typegoose.ts:87)
    at Module../src/model/RmfCategoryGroup.ts (RmfCategoryGroup.ts:17)

If i activate debug on typegoose i have the following traces before error:
