Fetch origin using worker endless loop

I'm trying to do something using a worker on a route before passing the request on (to cache, origin, etc.). I think I should be able to just call fetch() on the original request, but that puts me in an endless loop of the worker calling itself.
Can someone hit me on the head real quick? :NotLikeThis:

export default {
  async fetch(request, env, ctx) {
    // Do something else
    // ..
    
    // Fetch origin
    return await this.fetch(request)
  },
};

export default {
  async fetch(request, env, ctx) {
    // Do something else
    // ..
    
    // Fetch origin
    return await this.fetch(request)
  },
};

Is your worker setup as a worker route through Websites -> your.domain -> Worker routes? Also did you confirm that the request.url is the one that you expect it to be? This won't work I think on something like the .workers.dev domains.

Yes, it's setup like that request.url is what I expect

Is your origin hosted on cloudflare?

Run Cloudflare Workers while maintaining cached HTML delivery

I'm caching HTML content on Cloudflare and would like to replace client-side pixel tracking with pure server-side tracking - without any client-side initiation. I would like to use Cloudflare Worke...

What might be interesting to run is to go to your cloudflare account dashboard and go to Trace (beta), maybe that might reveal something interesting!
