How do you removing a item from local store array properly

[Aeseir]

Heya,

I have scenario where I obtain list of cars based on dealership Id.
A user/staff member can "remove" car from dealership (e.g. sale, or transfer etc.) in which case we trigger a mutation remove car from dealership as per below.

removeCarFromDealership = (input: { dealershipId: string, carId: string }) => this.apollo.mutate<any>({
  mutation: gql`
    mutation RemoveCarFromDealership($input: RemoveCarFromDealershipInput!) {
      removeCarFromDealership(input: $input) {
        boolean
      }
    }`,
  variables: {
    input: input
  },
  update: (store, { data: { removeCarFromDealership } }) => {
    if (removeCarFromDealership.boolean) {
      store.updateQuery({ query: GET_DEALERSHIP_CARS, variables: { dealershipId: input.dealershipId } }, (data: any) => ({
        cars: [...data.cars.filter((car: any) => car.id !== input.carId)]
      }));
    }
  }
}).pipe(map((result: any) => result.data.removeCarFromDealership.boolean));

Now this works however I get the following warning/error appear every time

Cache data may be lost when replacing the cars field of a Query object.

So question is what is the proper approach to remove an item from array in the local cache?
