404 page doesn't render in HTML but plain text

[roshanjonah]

Hi there,

I think this is a bug in Cloudflare Workers.

We are using Hugo and Cloudflare workers to push our static site, and Github does the automatic build and push.

% curl -svo /dev/null https://jonahnz.com/404.html

• Trying 104.21.25.56:443...
• Connected to jonahnz.com (104.21.25.56) port 443 (#0)
  ...
  < HTTP/2 200
  < date: Thu, 05 May 2022 16:55:39 GMT
  < content-type: text/html; charset=utf-8
  < content-length: 1159

That seems to have content type but not this random 404 address:
% curl -svo /dev/null https://jonahnz.com/non-existing-URL

• Trying 104.21.25.56:443...
• Connected to jonahnz.com (104.21.25.56) port 443 (#0)
  ...
  < HTTP/2 404
  < date: Thu, 05 May 2022 16:57:03 GMT
  < content-length: 1159

For some odd reason, the HTML is not rendering so if there is a non-existing URL like https://jonahnz.com/randskdfskuh - you can see it displays just raw HTML rather than outputting this page https://jonahnz.com/404.html

This behavior doesn’t come for free with Workers but it does with Pages. Sounds like you should be using that for this project — you can still deploy a sibling Worker alongside your Pages project if you have any dynamic endpoints
