Deploying with github not working after first commit, getting "there is nothing to commit"

[hshackle]

I'm trying to get this set up with my Github account. I set up my website locally and push it to the main branch on Github. Everything deploys as expected, the gh-pages branch shows up, and I'm able to view the website. Now I make some edits to the website and push to main. I get a green checkmark but nothing changes on my website. Looking at the logs under build-and-deploy seems to show the issue:

Note: switching to 'ac4eac188c9f7dcab516d5171bf138f4ca48f5bc'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Somehow the changes are not being registered and not being pushed to gh-pages? I'm not sure what's going on here. Full logs here: https://pastebin.com/uaUx3Lz3
