[kooriookami]

The result of const block = descriptor.styles[index]; could be undefined.

I'm not sure the issue, can you give an reproduction for this?

@underfin Well, I try to make a small demo, but failed. May be it will happen in multiple style scripts. Like this:

<style lang="scss" src="../styles/common.scss"></style>
<style lang="scss" src="../styles/base.scss"></style>
<style lang="scss" scoped>
...
</style>
<style lang="scss">
...
</style>
<style lang="scss" src="../styles/dialog.scss"></style>

I print the value of descriptor.styles.length and index. The descriptor.styles.length is obviously wrong. I think it may be the compiler's mistake. For workaround, I have to change scoped: !!block.scoped to scoped: !!block?.scoped.


If you need any other infomation, I can provide to you.
