updating a value of an object inside if statement not working

i have this function mapLocationOverrides it take two parameters items and locationId

inside the function i have a variable variations which filters trough items and returns all the items with the object location_overrides. then im looping through variations and every time the if statement is true the im not able to log data ousid that foreach loop it keeps breaking.

function mapLocationOverrides(items, locationId) {

  let variations = _.flatMap(items, 'variations').filter(v => {
    return 'location_overrides' in v && v.location_overrides.length;
  });

  _.forEach(variations, v => {
    let locationOverride = _.find(v.location_overrides, ['location_id', locationId]);

    if (locationOverride.price_money) {
      v.price_money = locationOverride.price_money;
      delete v.location_overrides;
    }

  });
  return items;
}
