Zod type mismatch

[muezz]

Disclaimer: I am not a 100% sure if this is a zsa bug or my mistake.

I have the following zod schema:

export const TableParamsSchema = z
  .object({
    page: z.coerce.number().positive().default(1),
    size: z.coerce.number().positive().default(10),
    hide: z
      .union([z.string().transform((val) => [val]), z.array(z.string())])
      .default([]),
    selected: z
      .union([z.string().transform((val) => [val]), z.array(z.string())])
      .default([]),
    order: z
      .union([z.string().transform((val) => [val]), z.array(z.string())])
      .transform((val) =>
        val.map((v) => {
          const parts = v.split(".");
          return {
            column: parts[0],
            direction: parts[1],
            ascending: parts[1] === "asc",
          };
        })
      )
      .refine((val) => val.every((v) => ["asc", "desc"].includes(v.direction)))
      .default([]),
  })
  .transform((val) => {
    return {
      ...val,
      end: val.size * val.page,
      start: val.size * val.page - val.size,
    };
  });

It looks fairly complicated but at the end of the day, it just parses and validates the search params related to some table operations.

Here is a zsa server function:

export const getHostingTickets = createServerAction()
  .input(
    z.object({
      filter: z.string().optional(),
      completed: z.boolean().default(false),
      before_today: z.boolean().default(false),
      id_client: z.string().uuid().optional(),
      sites: z.array(z.string()).default([]),
      models: z.array(z.number()).default([]),
      tableParams: TableParamsSchema.optional(),
    })
  )
  .handler(async ({ input }) => {
    // I do what I need to do here. All inferred types in "input" are 100% correct.
  });

Here is how I call this server function:

const tableParams = TableParamsSchema.parse(searchParams);

  console.log(tableParams);

  const [data, err] = await getHostingTickets({
    filter: searchParams.filter,
    models: searchParams.miner_model,
    sites: searchParams.site,
    completed: completed,
    tableParams: tableParams,
  });
  if (err) throw err;

The console log shows correctly validated data in the correct form. But tableParams in the input is underlined and says this:

This error goes away as soon as I remove the transform from the order property.
