Fix TRPCClientError

✅ Solution

TRPCClientError usually arises when the server-side TRPC procedure throws an error that isn't properly serialized or handled by the client. To fix it, ensure server-side errors are instances of `TRPCError` from `@trpc/server`, and that your client-side code correctly handles `TRPCClientError` by checking its `TRPC_ERROR_CODE_KEY` to determine the specific server-side error.
