小程序误报 Property "xx" was accessed during render but is not defined on instance

[justnewbee]

最小重现代码

<template>
  <view>{{ num }}</view>
</template>

<script lang="ts" setup>
const num = 12345;
</script>

结果

H5 没有问题

小程序报错「[Vue warn]: Property "num" was accessed during render but is not defined on instance. 」

l miss add "setup" in

[justnewbee]

l miss add "setup" in

every script in my project uses setup, and this only happens in mp not H5, after i updated the dependencies.

it sure is a regression bug.
