TypeScript Issue: router.createCaller Implicitly has Return Type "any"

import { UpdateProfile } from "@acme/validation/user";
import { type CallerContext } from ".";
import { createTRPCRouter, protectedProcedure } from "../common/trpc";

export const userRouter = createTRPCRouter({
  // ... (Other procedures)
  update: protectedProcedure
    .input(UpdateProfile)
    .mutation(async ({ ctx, input }) => {
      const user = await ctx.prisma.user.update({
        where: { id: ctx.auth.userId },
        data: input,
      });

      return userCaller(ctx).someOtherAction();
    }),

  someOtherAction: protectedProcedure.mutation(async ({ ctx }) => {
    const user = await ctx.prisma.user.findUnique({
      where: { id: ctx.auth.userId },
    });

    return user;
  }),
});

export const userCaller = (ctx: CallerContext) => userRouter.createCaller(ctx);
