Question

Subject: Workers not applied
I've just added a Worker on the Cloudflare Dashboard for my website: it works in the debugger but doesn't work when I
query the site. Why is that? Is there anything to activate or anything I could check?

Answer

Hello,

Thanks for reaching out to Cloudflare support.

Can you please confirm with which domain you are experiencing this issue? I checked the two domains in your account and none have a Worker Route set up.

If you are talking about either of these two domains, you would first need to configure the route for the respective Worker at https://dash.cloudflare.com/?to=/:account/:zone/workers.

Please also see https://developers.cloudflare.com/workers/configuration/routing/routes/ for further details on this topic.

Thank you very much,
Alexander

Reasoning

There could be other reasons of course, but here I assume the customer did not map the Worker to his domain.

Tools to use: n/a, maybe curl once it is working, but depends
