Deno Imports

I'm trying to use react-hook-form in an application, but bringing in the dependency results in a dependencies mismatch it appears. My import map includes the following:

{
  "imports": {
    "react": "https://esm.sh/v119/react@18.2.0",
    "react-dom/client": "https://esm.sh/v119/react-dom@18.2.0/client",
    "react/": "https://esm.sh/v119/react@18.2.0/",
    "react-dom": "https://esm.sh/v119/react-dom@18.2.0",
    "react-hook-form": "https://esm.sh/v119/react-hook-form",
  }
}

{
  "imports": {
    "react": "https://esm.sh/v119/react@18.2.0",
    "react-dom/client": "https://esm.sh/v119/react-dom@18.2.0/client",
    "react/": "https://esm.sh/v119/react@18.2.0/",
    "react-dom": "https://esm.sh/v119/react-dom@18.2.0",
    "react-hook-form": "https://esm.sh/v119/react-hook-form",
  }
}

I then use it like so:

import { useForm, SubmitHandler } from "react-hook-form";
import { ChangeEvent, useReducer } from "react";

function index(){
  const {} = useForm()
  return (/*...*/
}

import { useForm, SubmitHandler } from "react-hook-form";
import { ChangeEvent, useReducer } from "react";

function index(){
  const {} = useForm()
  return (/*...*/
}

When I load this route, however, the application crashes with the following error:

I'm pretty new to Deno, so I'm trying to parse this and understand what I should be doing instead.

Do you have a github repo or something you can share? Happy to look into that
