for debug

What steps can reproduce the bug?

After update 1.4.16 -> 1.4.17+ response validation loose errors (return empty array in error.all and empty summary).

For debugging:

import { describe, expect, it } from 'bun:test'
import { Elysia, t } from 'elysia'

const app = new Elysia({
    aot: false,
})
    .post(
        '/test',
        () => {
            return {
                items: [
                    ['t1', { file: { ver: { s: '', m: null } } }],
                    ['t2', { file: { ver: null } }], // invalid response
                ],
            }
        },
        {
            body: t.Object({ }),
            response: t.Object({
                items: t.Array(t.Tuple([
                    t.String(),
                    t.Union([
                        t.Object({
                            file: t.Object({
                                ver: t.Object({
                                    s: t.String(),
                                    m: t.Nullable(t.String()),
                                }),
                            }),
                        }),
                    ]),
                ])),
            }),
        },
    )

describe('POST /test', () => {
    it('correct response', async () => {
        const req = new Request('http://localhost/test', {
            method: 'POST',
            headers: { 'Content-Type': 'application/json' },
            body: '{}',
        })
        const res = await app.handle(req)
        const txt = await res.text()
        console.error(txt)
        expect(res.status).toBe(422)
    })
})

What is the expected behavior?

Test passed

What do you see instead?

Error 500
null is not an object (evaluating 'ar0p[1].file.ver.s')

Additional information

In real application response schema is huge, with aot = true - response 422, but error summary is empty.

Have you try removing the node_modules and bun.lockb and try again yet?

yes
