[ilyhalight]

What version of Elysia is running?

1.2.24

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What steps can reproduce the bug?

import { Elysia, t } from "elysia";

const testModel = new Elysia().model({
  sign: t.Object({
    username: t.String(),
    age: t.Number(),
  }),
});

const app = new Elysia()
  .use(testModel)
  // to check error in console (not necessarily)
  .onError(({ error }) => {
    console.log(error);
  })
  .post("/", ({ body }) => body, {
    body: "sign",
  })
  .listen(3000);

console.log(
  `🦊 Elysia is running at ${app.server?.hostname}:${app.server?.port}`
);

What is the expected behavior?

  "type": "validation",
  "on": "body",
  "summary": "Property 'age' is missing",
  "property": "/age",
  "message": "Expected required property",

Runtime: Bun 1.2.4
