I get a 400 status code error from a GitHub Pages deployment

Question

During an automated "pages build and deployment" workflow, I get the following error:

Error: Request failed with status code 400

This is just a static site, no jekyll or anything like that (I have a .nojekyll file in the root) and it's worked fine for several years until today.

I've opened a ticket on GitHub support, but in case anyone here can help me in the meantime... Is there anything I can do to try to resolve this?

GitHub Pages: using GitHub Actions for builds and deployments for public repositories

Today you will begin to see a new workflow running called pages build and deployment in your public GitHub Pages repositories.

This workflow is automatically triggered when you push to the branch configured for GitHub Pages in your repository.
As the name suggests, it builds and deploys your pages site.

The initial benefit of this change is enabling you to see your build logs and any errors that may occur which has been a long standing issue for Pages users.
However, in the future this will enable us to give you the ability to fully customize your pages build and deployment workflow to use any static site generator you want without having to push the build output to a special branch of the repository.

You may notice this workflow uses some new actions actions/pages-deploy , and actions/jekyll-build-pages .
For now these actions are designed to be used in the generated workflow, however, starting early next year we will introduce some additional changes that will enable you to take advantage of them.

So Cecilapp/GitHub-Pages-deploy (the GitHub Pages deploy ) workflow you might be using) might behave differently in light of those recent changes.
