Problem

Vetur is reporting the parameter is of type unknown even though TypeScript is able to derive the type GetLoggedInUserQuery.

Edit:
Cannot build the app because of this.

Reproducible Case

1. Setup @vue/composition-api for Vue 2
2. Setup @vue/apollo-composable
3. Use the useResult() helper of @vue/apollo-composable on your GraphQL query.
4. Use the parameter (data from the screenshot) of the function from the third argument of the useResult() function.
5. Vetur will report:

Object is of type "unknown".

Even though TypeScript is able to derive the correct type.

Can you push a minimal repro sample to GitHub so I can clone and find the issue?

[cerino-ligutom]

@octref Sure, here

Any temporary workaround for this?

@octref Sure, here

I can't reproduce it.

Can you give me information when you hover useResult?

The vue-cli-service isn't vetur problem,
but I also study about it.

1. You're missing two libraries (apollo-client graphql) in this repos.
2. useGetLoggedInUserQuery have a type error.
3. The @vue/apollo-composable library have a type error.

Maybe third problem is type problem in @vue/apollo-composable library,
You can skipLibCheck: true in tsconfig.json for ignore it.

I fixed them, and then the project will build success.
