SSR TypeError: Cannot read properties of null (reading 'useState')

I'm trying to use deno task start but it's failing.

Steps:

1. Run deno run -A -r https://alephjs.org/init.ts
2. Choose React, and yes to all
3. Run deno task start
4. You get greeted with this

try to execute deno cache -r https://esm.sh/react@18.2.0

[omar2205]

It fixed the generated template. Now when I try to add this code it breaks again with

Cannot read properties of null (reading 'useState')

import { useEffect, useState } from "react"
// ...

  const [c, setC] = useState(0)

  useEffect(() => {
    const i = setInterval(() => {
      setC(c + 1);
    }, 500)
    return () => clearInterval(i)
  }, [])

please change "react": "https://esm.sh/react@18.2.0" to "react": "https://esm.sh/v113/react@18.2.0" in your import map and jsxImportSource in deno.json

where you got the message? is devtools console?

[omar2205]
