If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

In development enviroment, partytown script loaded fine. But in production partytown script isn't loaded beacause of HTTP 404 error

I tested node and vercel adapters. Node adapter produced ~partytown directory, but vercel didn't. It might seem that vercel adapter with partytown doesn't work now.

What's the expected result?

vercel adapter produce partytown script and partytown should be loaded in a browser

It looks like when astro build process is started, adapter is called prior to integrations so vercel adapter doesn't copy partytown script because partytown paste script to the output directory(/dist) after vercel copies from it. To fix this issue, adapter needs to be executed after all integrations are executed but I don't know how it effects applications that use astro because some apps might rely on execution order of integrations.

// before
settings.config.integrations.unshift(settings.config.adapter);
// after
settings.config.integrations.push(settings.config.adapter);

I am experiencing a similar issue where I am using an Astro compressor plugin. The compressed HTML files in the output folder differ from those in the .vercel/output/static folder when running astro build.
