Throw Validation error inside the procedure?

Yeah that's what I'm doing currently. Wraping into a TRPCError + errorFormatter that is already used for the input validation. Thought there would be an easier solution, but that's still fine enough:

export async function validate(
  path: string,
  condition: boolean | (() => Promise<boolean>),
  message: string = "",
) {
  try {
    type({
      [path]: type("true").configure({
        message: message ?? "Invalid value.",
      }),
    }).assert({
      [path]: typeof condition === "function" ? await condition() : condition,
    });
  } catch (e) {
    throw new TRPCError({
      code: "BAD_REQUEST",
      cause: e,
    });
  }
}

export async function validate(
  path: string,
  condition: boolean | (() => Promise<boolean>),
  message: string = "",
) {
  try {
    type({
      [path]: type("true").configure({
        message: message ?? "Invalid value.",
      }),
    }).assert({
      [path]: typeof condition === "function" ? await condition() : condition,
    });
  } catch (e) {
    throw new TRPCError({
      code: "BAD_REQUEST",
      cause: e,
    });
  }
}
