No need to add sugar to the mashed purple potatoes, it's already very sweet. If you don't have honey beans, you can replace them with bean paste. Be sure to roll out the rice with plastic wrap to avoid sticking. It's easier to use a sushi roll curtain to help shape the cake. When cutting the cake body, the knife can be dipped in water, it will be better to cut.
