Why typescript value becomes of type "any"

Question

So it seems that for some reason, not sure who's fault it is - typescript type is not being recognized...

As an example, I'm using "pinia@next" npm package, and here's a simple demo code:

(This is the only file in the folder together with single package installed npm install pinia@next)

import { defineStore, Store } from "pinia";

export type State = {
  anyProperty: string
};

export const useAccountStore = defineStore("account", {
  state: () => ({} as State),
});

var test = useAccountStore() as Store<"account", State>;

And in this piece of code:

1. "useAccountStore" has a correct type
2. "StoreDefinition" type is a function that returns "Store" as a return type:
3. VS Code thinks it returns an "any" type:

4. Even, when I explicitly cast it to "Store" type, it results in "any"

• VS Code version: 1.64.1
• VS Code typescript version: 4.5.5

Any ideas what might be happening?

• It doesn't seem to be an issue with package itself, as I haven't found any similar issues on the internet as well as on tutorials on YouTube I can see that people are getting strong type without any additional steps... Thus this must be an issue with my Typescript configuration/version or something?
• I did upgrade my Visual Studio Code to latest version
• In Visual Studio Code dev tools - I cannot see no warnings nor errors related with typescript
