This is my code

gatsby-ssr.js file

`import React from "react";
import { Partytown } from "@builder.io/partytown/react";

export const onRenderBody = ({ setHeadComponents, setPreBodyComponents }) => {
//const gtmTrackingId = process.env.GATSBY_GOOGLE_TAG_MANAGER_TRACKING_ID;
setHeadComponents([
<Partytown key="partytown" debug={true} forward={["dataLayer.push"]} />,
<script
key="plugin-google-tagmanager"
type="text/partytown"
dangerouslySetInnerHTML={{
__html: (function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src= 'https://www.googletagmanager.com/gtm.js?id='+i+dl+'';f.parentNode.insertBefore(j,f); })(window,document,'script','dataLayer', 'GTM-KXJZBP');,
}}
/>,
<script
key="partytown-vanilla-config"
dangerouslySetInnerHTML={{
__html: partytown = { resolveUrl(url, location) { if (url.hostname === "www.google-analytics.com" && url.pathname.endsWith(".js")) { var proxyUrl = new URL('http://localhost:9000/google-analytics'); proxyUrl.searchParams.append("url", url.href); return proxyUrl; } if (url.pathname.includes("/debug/bootstrap")) { var proxyUrl = new URL('http://localhost:9000/googletagmanager/debug/bootstrap'); proxyUrl.searchParams.append("url", url.href); return proxyUrl; } return url; } },
}}
/>,
]);

setPreBodyComponents([
<noscript
key="gtm"
dangerouslySetInnerHTML={{
__html: <iframe src="https://www.googletagmanager.com/ns.html?id=GTM-KXJZBP" height="0" width="0" style="display: none; visibility: hidden" aria-hidden="true"></iframe>,
}}
/>,
]);
};`

gatsby node.js file

`exports.onPreBuild = async ({ actions: { createRedirect } }) => {
await copyLibFiles(path.join(__dirname, "static", "~partytown"));

createRedirect({
fromPath: /google-analytics?url=:url,
toPath: :url,
statusCode: 200,
});

// This is only for GTM preview mode for debugging
createRedirect({
fromPath: /googletagmanager/debug/bootstrap?url=:url,
toPath: :url,
statusCode: 200,
});
};`
