Intellisense (Go to Definition/Peek) of methods doesn't work if I have computed property within same .vue file

[bahung1221]

• I have searched through existing issues
• I have read through docs
• I have read FAQ
• I have tried restarting VS Code or running Vetur: Restart VLS

Info

• Platform: macOS
• Vetur version: 0.19 -> 0.28.0 (I tried to downgrade through a lot of vetur versions but it still doesn't work)
• VS Code version: 1.49 -> 1.50 (latest)

Problem

I can't call go to definition or peek definition of all methods when I have any computed property that was declared in the same vue instance, both call from script and template just showed "No definition found for...".
If I remove computed, It will work fine!

I also tried to removed all extensions and then reinstall both vscode and vetur but no luck.
You can check the reproduce repository below that I successfully reproduced.

Reproducible Case

Just install vscode and install only vetur and then try to create a method and a computed property that use this instance inside .vue file.

Thanks for your respond, it worked now 😄

For those who don't use vue with typescript, just add typescript < v3.4 to your project devDependencies:

yarn add -D typescript@3.2.4

Then add "vetur.useWorkspaceDependencies": true, to your vscode setting.
