Number Array not work

[royyoung388]

Array with number not working. When I click add button, it disappeared.
Array with string works fine.

here is my json schema:

{"type":"object","properties":{"array":{"type":"array","items":{"type":"number"}}},"additionalProperties":false,"title":"test1","description":"","$id":"#/schema/test1/0.4","$schema":"https://json-schema.org/draft/2020-12/schema"}

here is ui code in Vue3:

<template>
	<jsf-shoelace .schema="schema" .data="state.data" .ui-schema="{}"></jsf-shoelace>
</template>

What I got before click:
