Ent just ensures that you get the same colo. I don't remember off the top of my head, but Email Workers might run in a colo that wouldn't be served by a lower-tier plan

Hey everyone, I have a worker that I have set to run every 5 minutes and have been manually triggering it to test it and have noticed that it works when I trigger it but not via the cron job?

  async fetch(request, env, ctx) {
    await this.scheduled(request, env, ctx);
    return new Response("don");
  },

...

  async scheduled(event, env, ctx) {
    const data = await this.getAllDataInD1(env);
    const description = data.map(rank => `${rank.tierName} (${rank.rankScore})`).join('\n');
    await editWebhook(description);
  },

thats actually showing up on the page as text/plain (so just the html as written), and if i add the headers

                        }

                        }
                        return new Response(mesRes);

                        }

it shows up as object Object

W

Walshy•5/7/25, 6:26 PM

https://developer.mozilla.org/en-US/docs/Web/API/Response/Response

first param for Response is the body, you'll want

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

return new Response(html, { headers: { 'Content-Type': 'text/html' } });

MDN Web Docs

Response: Response() constructor - Web APIs | MDN

The Response() constructor creates a new Response object.

S

Senti3ntB3ing•5/7/25, 6:27 PM

thank you! so trying to form the json myself there, with headers, body, doesn't work because it expects the body first, and then a headers obj after?
