Invalid State after copying and pasting example code 2

I am using @auth0/auth0-spa-js in a React project. I copied and pasted the code from the tutorial and I am getting an invalid state error (I changed some location vars to window.location). I was using the Auth0Provider previously, so the connection should be good.

My code:

  async loadLogin() {
    createAuth0Client({
      domain: "domain",
      clientId: "id",
      authorizationParams: {
        redirect_uri: window.location.origin
      }
    }).then(async (auth0Client) => {
      // Assumes a button with id "login" in the DOM
      const loginButton = document.getElementById("login");

      loginButton?.addEventListener("click", (e) => {
        e.preventDefault();
        auth0Client.loginWithRedirect();
      });

      if (window.location.search.includes("state=") && 
          (window.location.search.includes("code=") || 
           window.location.search.includes("error="))) {
        await auth0Client.handleRedirectCallback();
      window.history.replaceState({}, document.title, "/");
      }

      // Assumes a button with id "logout" in the DOM
      const logoutButton = document.getElementById("logout");

      logoutButton?.addEventListener("click", (e) => {
        e.preventDefault();
        auth0Client.logout();
      });

      //const isAuthenticated = await auth0Client.isAuthenticated();
      //const userProfile = await auth0Client.getUser();

      //// Assumes an element with id "profile" in the DOM
      //const profileElement = document.getElementById("profile");

      //if (isAuthenticated) {
        //profileElement?.style.display = "block";
        //profileElement?.innerHTML = `
        //<p>${userProfile.name}</p>
        //<img src="${userProfile.picture}" />
        //`;
      //} else {
        //profileElement.style.display = "none";
      //}
    });
  }

The error:
