Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

My blog's home page contains links to the feed files:

[rss](/blog/rss.xml)   [atom](/blog/atom.xml)   [json](/blog/feed.json)

Until Docusaurus 3.0.0, the site was built successfully, but starting in 3.1.0, this error happens:

  [cause]: Error: Docusaurus found broken links!
 
  Exhaustive list of all broken links found:
  - Broken link on source page path = /:
     -> linking to /blog/rss.xml
     -> linking to /blog/atom.xml
     -> linking to /blog/feed.json

Reproducible demo

https://github.com/Zwyx/zwyx.dev

Steps to reproduce

In https://github.com/Zwyx/zwyx.dev, the branch main builds correctly, the branch update-docusaurus doesn't.

Expected behavior

Links to feed files shouldn't be detected as broken.

Actual behavior

Links to feed files are detected as broken.

Your environment

• Public source code: https://github.com/Zwyx/zwyx.dev
• Public site URL: https://zwyx.dev
• Docusaurus version used: live site: 3.0.0, update-docusaurus branch: 3.1.1
• Environment name and version (e.g. Chrome 89, Node.js 16.4): N/A
• Operating system and version (e.g. Ubuntu 20.04.2 LTS): N/A

Self-service

• I'd be willing to fix this bug myself.

This is the same problem as the one described here: #9803

You do have broken links if you click on the RSS feed link (without middle click, do not open the feed in new tabs)

You should use the pathname:// protocol to link to any page or resource that is not an SPA route known by Docusaurus. Otherwise it won't work when navigating that link.

See my answer here in particular: #9803 (comment)

I can't believe I never noticed these links were broken 🤦 I've always middle-clicked them...

Thank you very much and apologises for this silly mistake.

That's our fault, we should have told you 😄
