the reason why validator middleware return errors when z.number()

[PorcoRosso85]

Hi.
This code returns error as below.

const schema = z.object({
  id: z.number(),  // z.string() is working
  user: z.string(),
  content: z.string(),
});

app
  .post(
    "/add",
    validator("form", (v, c) => {
      const parsed = schema.safeParse(v);
      return parsed.success ? parsed.data : c.text("invalid", 401);
    }),

No overload matches this call.
  The last overload gave the following error.
    Argument of type 'MiddlewareHandler<any, string, { in: { form: { id: number; user: string; content: string; }; }; out: { form: { id: number; user: string; content: string; }; }; }>' is not assignable to parameter of type 'H<Env, "/add", Input, Promise<Response>>'.
      Type 'MiddlewareHandler<any, string, { in: { form: { id: number; user: string; content: string; }; }; out: { form: { id: number; user: string; content: string; }; }; }>' is not assignable to type 'MiddlewareHandler<Env, "/add", Input>'.
        Types of parameters 'c' and 'c' are incompatible.
          Type 'Context<Env, "/add", Input>' is not assignable to type 'Context<any, string, { in: { form: { id: number; user: string; content: string; }; }; out: { form: { id: number; user: string; content: string; }; }; }>'.
            Types of property 'var' are incompatible.
              Type 'Readonly<Variables | undefined>' is not assignable to type 'Readonly<any>'.
                Type 'undefined' is not assignable to type 'Readonly<any>'.ts(2769)
types.d.ts(58, 5): The last overload is declared here.

Is there the way to use validation for any types instead of string?
I'm sorry if this question has already solved despite that I've checked issues

Hi @PorcoRosso85,

If you're validating a form, the values will always be of type string because that's how they're defined in TypeScript. Btw, if you set the input as json, the values can be of types number or boolean.

For converting a string to number and validating it, you might find this comment helpful:

Thanks.
Will check converting also.
