plasmo [BUG] useStorage not persistent

What happened?

useStorage is not persistent when refreshing a page. Here's my content.tsx :

const Content = () => {
  const [hello, setHello] = useStorage("hello", (v) => {
    return v === undefined ? {} : v
  })

  useEffect(() => {
    console.log(hello)
    const random = Math.floor(Math.random() * 50)
    setHello({ ...hello, [random]: "test" })
  }, [])

  return <button>OK</button>
}

export default Content

console.log give undefined

Describe your issue next time more clearly. It is hard to help you this way. I can only guess, but I believe using: setHello((prevState) => ({ ...prevState, [random]: "test" })) will fix your issue.

Sorry, I will try to explain it better. When a page is loaded I want to add a key in the object "hello" on the storage. But the console.log(hello) in useEffect is always undefined (so it is not persistant otherwise it will contains the key added from the last loaded page). If I reload a page three time I expect it to contain 3 random key. I tried this :

setHello(prevState => {
   console.log(prevState) // => undefined;
   setHello({...prevState, [random]: "test"})
})

But it is the same.

For more clarity :

const Content = () => {
  const [hello, setHello] = useStorage("hello", (v) => {
    console.log("A", v)
    return v === undefined ? {} : v
  })

  useEffect(() => {
    setHello((prevState) => {
      console.log("B", prevState)
      const random = Math.floor(Math.random() * 50)
      return { ...prevState, [random]: "test" }
    })
    console.log("C", hello)
  }, [])

  return <p>Hello</p>
}
