Unable to read data using usei18n in the page

[SnowGuest]

vue-i18n@9
const i18n = createI18n({
legacy: false,
globalInjection: true,
messages:[
{“zh-cn”:{message:"msg"},
{“en”:{message:"msg"},
]
});

// views/pageA.vue

<script setup> const {t} = useI18n(); t("message"); // Unable to get characters </script>

I checked the return value of usei18n in the page. It is the same as the ID when creating, and the messages are also correct, and isGlobal is true. Strangely, it cannot be read

And there is another problem, I have zh-CN and en but I never added zh, but zh appears in the warning
