Description

Yesterday I found that the output (=artifact on github actions) produced by running github actions(ubuntu-22.04) and my windows local computer are different. The root page(https://example.com), (root)/index.html, shows the contents written on about.md, which is completely unexpected and not occur on my local environment (not gatsby develop, but gatsby build). This should render contents on index.md on (root)/index.html.

I confirmed like three times that I do not using the wrong or different npm, yarn, and ubuntu version on both computers.

Detailed description is also below. This issue is already solved for me by changing build OS to windows-latest, so this is not a question but dedicated for a bug report.

Repository causing the issue

https://github.com/AoSankaku/aosankaku.github.io

You can confirm the issue by cloning and building a website using github actions. Please do not try to make this public because the contents (articles, images) are lisenced under All Right Reserved.

Branch cee5bf44dc3f99a0e8e410d481ed14e0f44daf5c is working fine, and branches until a40ae460e22fa2110f06c184ac8cc6d97a3f8460 is behaving badly.

Artifacts (Outputs)

Artifact that is created by ubuntu-22.04

github-pages.zip

Artifact that is created by windows-latest(windows-2022)

github-pages1.zip

My own gatsby build result (contains some files which is unused in production build)

Reproduction Link

Steps to Reproduce

1. Clone the repo
2. Set up github actions using yarn build (gatsby build)
3. Run the workflow
4. Produces kinda unexpected output (artifact)

Do not use the latest build to reproduce the issue, as this is fixed by using windows-latest instead of ubuntu-22.04.
I'm saying that this is strange that on windows and on ubuntu the gatsby build result must not differ from each other.

Expected Result

Produces the same website (at least the contents and pages on the website!) on both windows and ubuntu environment

Actual Result

The production build on windows and ubuntu are different on index.html.
