async policies() {
    let objects = [];
    try {
      const orderList: any = await this.orderRepository.getAllOrders();
      const val: any = orderList.orders.map(async (order: any) => {
      const res: any = await this.policyRepository.getPolicies(helper.sliceOrderId(order.name));
      return res;
    });
    Promise.all(val).then((obj: any) => {
      objects = [...objects, ...obj.items];
      // console.log('dcc', obj);
    });

    return objects;
  } catch (er) {
    return this.errorResolver.resolve(er);
  }
}

In this function I'm getting orders and calling another function with the value, I am calling another function to retrieve all policies. When I did use from Promise.all function. I wanted to store the values to the local variable in the objects variable. but still, it's showing an empty array eventually. I don't know why the data isn't updating.
