Describe the bug

We are trying to load and trigger google tag manager events by using partytown. It doesn't trigger the gtm events. It is implemented in NextJS.

Here is the configuration in _document.tsx

<Partytown
                        debug
                        logCalls
                        logGetters
                        logSetters
                        logImageRequests
                        logMainAccess
                        logSendBeaconRequests
                        logStackTraces
                        logScriptExecution
                        forward={["dataLayer.push"}
                    />

Here is the google tagmanager script:

<script
                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','tag-manager-id');`
                }}
            />

I tried to find the issue by debugging. I am just able to see this log:

partytown-ww-sw.js:1611 Fetch failed loading: POST "https://www.google-analytics.com/g/collect?v=2..."

Reproduction

We reverted it on the prod. We test it locally.

Steps to reproduce

• initialize the Partytown in NextJS
• forward "dataLayer.push" in partytown
• copy the Google Tag Manager script that is shown in the description and use it with the GTM ID

Thanks for opening this issue. I will try to spin up a NextJS app to reproduce the issue
