Reproduction

See this stackblitz
https://stackblitz.com/edit/qwik-starter-fqky5z?file=src%2Froot.tsx

Steps to reproduce

Add a tag similar to the one below at root layout:

<script async type="text/javascript" dangerouslySetInnerHTML={` (function(w,d,t,r,u){var f,n,i;w[u]=w[u]||[],f=function(){var o={ti:"12345678"};o.q=w[u],w[u]=new UET(o),w[u].push("pageLoad")},n=d.createElement(t),n.src=r,n.async=1,n.onload=n.onreadystatechange=function(){var s=this.readyState;s&&s!=="loaded"&&s!=="complete"||(f(),n.onload=n.onreadystatechange=null)},i=d.getElementsByTagName(t)[0],i.parentNode.insertBefore(n,i)})(window,document,"script","//bat.example.com/bat.js","uetq"); `}></script>

Additional Information

This isn't a critical bug as it only happens locally - since the optimizer only runs in Dev mode. But annoying since this appears on every single page load. especially if the script above was added at root.

Interesting. Could you make a more specific test case, as short as possible?

Note that in the playground it doesn't seem to happen, so maybe there's an issue with the Rust build, or wasm is more forgiving:

I see now that the stack of the error isn't the optimizer at all, the bundle file just happens to be named that way. It's inside getInfoForSrc, which is a js-only fetch to get information about an image. So the issue is in nodejs or so, not Qwik
