Issue when schema has coerce and async refine

[LucasSFranco]

I'm getting a weird error when using coerce with an async refine.

I have this validation schema:

const schema = {
  id: z.coerce
    .number()
    .int()
    .pipe(
      z.number().refine(async (id) => this.exists(id), {
        message: "Not found",
      })
    )
}

The doc generation:

registry.registerPath({
  method: "get",
  path: "...",
  summary: "...",
  description: "...",
  request: {
    query: schema,
  },
  responses: {
    200: {
      description: "...",
      content: {
        "application/json": {
          schema: z.object({}),
        },
      },
    },
  },
});

It doesn't generate the docs. It is throwing the following error:

Error: Async refinement encountered during synchronous parse operation. Use .parseAsync instead.

If I remove the .coerce or the .refine, it generates the docs.

{
  id: z
    .number()
    .int()
    .pipe(
      z.number().refine(async (id) => this.exists(id), {
        message: "Not found",
      })
    )
}

or

{
  id: z.coerce
    .number()
    .int()
    .pipe(
      z.number()
    )
}
