vue2: no error will be reported with nonexistent data.Type is unknown

[hexf00]

I use https://github.com/johnsoncodehk/volar-starter vue2 branch.

I propose this issue because the Class API or Vue.extend performs better.

I don't understand how this difference is caused.

ts version:4.6.3 / 4.5.5
vscode version: 1.67.2
volar version: v0.34.16

Volar is doing very nice. I like volar. Thank you for your efforts and hope it can be better.

p.s I have been experiencing 5-minute crashes mentioned by other issues. I always restart vscode. I hope I can help you with this problem, but I don't know what I should do?

This is @vue/composition-api behavior from https://github.com/vuejs/composition-api/blob/032f2c75992043a02a61e05d5f1493d78738ae72/src/component/common.ts#L1.
