_resolveDef function access props but it is undefined

[AngryChocobo]

Vue version

^3.2.40

Link to minimal reproduction

https://stackblitz.com/edit/vitejs-vite-bjiedl?file=src/App.vue

Steps to reproduce

1. npm run dev
2. check console, will receive error: Uncaught TypeError: Cannot read properties of undefined (reading 'dataV7a7a37b1') at resolve2 (vue.js?v=f51652de:7665:28)

I am not sure vue version is 3.2.37.. I console log the varible in debuuger

What is expected?

Webcomponent can success render.

What is actually happening?

In runtime-dom.esm-bundler.js _resolveDef function props is undefined.

const hasOptions = !isArray(props)

We should also check the props is not undefined
PR welcome.

I did a PR for that already months ago. Seems ro have been drowned out a bit. #6182

So this issue is a duplicate, but the original issue seems to have been closed by the author.

So we'll leave this one.

@defaude So how can I skip this question? I am stucked. 😂

[LinusBorg]

i think a workaround was to define an empty props object in the component? Not sure, can't test right now

@LinusBorg Thanks. It works.

<script lang="ts" setup>
defineProps<{ somePatch: string }>();
</script>

Please don't close it, it's still so a bug 😅
