I'm trying to use generic type with vue composition API, and getting an error.

import { ref } from "vue";

function useContext<T extends BaseContext>(v: T) {  
 const context = ref<T | null>(null)  
 context.value = v  
 return {context}  
}

interface BaseContext {}  

src/main.ts:5:3 - error TS2322: Type 'T' is not assignable to type 'UnwrapRef<T> | null'.  

Is this a bug, or am i doing something wrong?
