Server Entrypoint is called after Server Function execution

Start

Describe the bug

I am having a weird issue, or maybe i understand the process wrongly:

I have defined a custom server entry point, as far as I understand this should be the very first thing that gets called on everything server related.

However, if I call a server function from a route loader, this one actually gets executed before my custom handler, so either i do something wrong or I dont understand how the server entrypoint should work?

Your Example Website or App

Steps to Reproduce the Bug or Issue

1. Open the root page in browser
2. Check the logs
3. Function logs are produced before server entry point logs

Expected behavior

Server Entry Point should be the very first thing that gets executed before any server function can run

your customHandler is running when router is handling the request. this is NOT the actual server entry.

you would need to use something like this instead:

const fetch = createStartHandler(customHandler)

export default createServerEntry({
  fetch: (req) => { 
    console.log('this is the server entry'); 
    return fetch(req);
   }
})
