Hello, why does undefineProps return unknown when defined?

[Evllis]

Library version

Vue.js version

Question

I searched on Google for a long time but couldn't find a solution to the problem

Looking at the code prompt, the methods all return results, but when declaring variables, the properties are all unknown. I don't know why Can you help me, thank you.

But when I use the original notation, I can access the target type, but I don't want to do this because compared to your plugin, this notation is too cumbersome

Hello, I tried to create a reproduction demo here: https://github.com/dwightjack/vitejs-vite-pktjcl. When I open the HelloWorld.vue component in VSCode I see the correct type:

Could you try to download it, install it (npm ci), and let me know if you see the correct typing as well?

[Evllis]

Okay, thank you. I'll give it a try and let you know once I have the results.

I just downloaded your demo and installed it, and I have correctly displayed the type here.

It seems that there is an issue with the configuration of my project, which affects the correct derivation of vue types.

Let me find out where the problem is.

Anyway, thank you for your help, thank you very much.

I have the same question
I think it was caused by the TS option 'strictNullChecks: false'
when I delete this row and restart vscode,the question is missing
