In theos most recent video on server actions in nextjs using the T3 stack, he gets an error https://youtu.be/PmBfq-SpzCU?si=kq1IhqH6-iptkh8v&t=508. I didn't catch what he did to solve it. I'm trying to do something similar. In my case, i just want to create a db entry using tRPC as a server action.
