How to delete a multiple fields from the data before saving ?

[akshayxemo]

I have tried to use beforeChange & beforeOperation Collection hook but it still storing the fields as it is. The Deleted fields are an group type field. Can anyone please tell me what I am doing wrong ?

import {
  CollectionBeforeChangeHook,
  CollectionBeforeOperationHook,
} from "payload/types";

export const dashboardConfigRemovenullPrograms: CollectionBeforeOperationHook =
  async ({ args, operation }) => {
    console.log(args.data);
    if (operation == "create" && args.data) {
      delete args.data.address; 
    /* also tired delete args.data["address"] & args.data.address = null; nothing working this 
    `address` is a "group" type field and consist of many sub fields. */
     delete args.data.config; // config is also same 
      console.log("final data before save: ", args.data);
    }
    return args;
  };
