form.setFieldValue with field array

const form = useForm<Partial<Recipe>>({
  defaultValues: {
    name: name ?? "",
    description: description ?? "",
    instructions: instructions ?? "",
    categories: [...(recipe?.categories ?? [])],
    ingredients: [...(recipeIngredients ?? [])],
    steps: [...(recipe?.steps ?? [])],
  },
  onSubmit: async ({ value }) => {

});

type SingleIngredient = Recipe["ingredients"][number];
const [tempIngredient, setTempIngredient] = useState<SingleIngredient | undefined>(
  undefined,

// Rest of component

form.setFieldValue(`ingredients[${index}]`, tempIngredient);

Argument of type '`ingredients[${number}]`' is not assignable to parameter of type 'PrefixObjectAccessor<Partial<Recipe>, []>'.
