readValidatedBody throws an error with inappropriate error message

[hecateball]

Environment

h3: 1.9.0
Node.js: v20.5.1

Reproduction

Call the readValidatedBody() function with validate that returns false.

details:
Initialize a nitro project(v2.8.1) and add a route file with following contents:

// routes/index.post.ts
export default defineEventHandler(async (event) => {
  const validate = () => false
  await readValidatedBody(event, validate)
})

Run the application and invoke the endpoint with curl -X POST 'http://localhost:3000'

Describe the bug

readValidatedBody(event, validate) throw an error with message "Cannot read properties of undefined (reading 'message')" if the validate returns false.
(Expected message here might be "Validation Failed")

Internal function createValidationError() accepts undefined as parameter, uses it without checking if it is undefined.

validateData actually calls createValidationError() with no parameter when ValidateFunction returns false.
