So if I tried to do this (without setting UUID manually)

    @Override
    public Mono<RestaurantGroup> createRestaurantGroup(String userId, RestaurantGroupCreateDTO restaurantGroupCreateDTO) {
        RestaurantGroup restaurantGroup = RestaurantGroupMapper.restaurantGroupCreateDTOToRestaurantGroup(restaurantGroupCreateDTO);
//        UUID uuid = UUID.randomUUID();
//        restaurantGroup.setId(uuid);
        return restaurantGroupRepository.save(restaurantGroup);
    }
#

It throws error as

null value in column \"id\" of relation \"restaurant_group\" violates not-null constraint"

#

If I tried to set manually (by uncommenting the lines)

Failed to update table [restaurant_group]; Row with Id [d3d8d8dd-305f-4cda-9e69-0d764d66837b] does not exist",

#

I use webflux

ok I found the solution
