How to use the json-pointer.get function in json-pointer

async _GET (path) {
    let result = null;

    if (path === '/') return this.state;

    try {
      result = pointer.get(this.state, path);
    } catch (E) {
      this.error(`Could not _GET() ${path}:`, E);
    }

    return result;
  }

validate (obj: any, context: Context, path: string = ''): Promise[] {
    obj = cloneDeep(obj)

    if (path !== '') {
      set(obj, path, this.parse(get(obj, path)))
      return super.validate(obj, context, path)
    } else {
      return super.validate(this.parse(obj), context, path)
    }
  }
}

export function get(entity: any, path: string): any {

    return jsonPointer.get(entity, path);
}
