Invalid Types.array() checking

[Louprenard]

Description
Some type checker in KsNumber used in combination with KsArray :
Edit : it also occurs with KsBoolean and KsString.

• When calling test1 with a = 3 then a = null, it behaves as expected (null is rejected but 3 is accepted)
• When calling test1 with a = null then a = 3, it behaves as expected (null is rejected but 3 is accepted)
• When calling test2 with [{ "a": 3 }] then [{ "a": null }], it behaves as expected (null is rejected but 3 is accepted)
• When calling test2 with [{ "a": null }] then [{ "a": 3 }], it treats the second as still being null (0.a: { "msg": "Cannot be null", "code": 3 })

Note that it may trigger a whole refresh of the app if used with tsc-watch, thus resolving the issue but not in a good way.

Packages
koa-smart@4.1.1
typescript@5.7.3

Minimal reproduction

import { Types, Route } from 'koa-smart';

@Route.Route({
  routeBase: '',
})
export default class RouteIndex extends Route {
  @Route.Post({
    bodyType: Types.object().keys({
      a: Types.number().required(),
    }),
  })
  async test1(ctx) {
    console.log(this.body(ctx));
  }

  @Route.Post({
    bodyType: Types.array().type(Types.object().keys({
      a: Types.number().required(),
    })),
  })
  async test2(ctx) {
    console.log(this.body(ctx));
  }
}
