My site name is deploja-site.netlify.app
As of writing, I have had to downgrade to 13.2, so the issue is not visible on this site.

The issue observed is that, intermittently, I will get a response starting with text, such as:
0:[["children",["slug","/slug","oc"], 1: ...
The issue is described here: Showing data dump in the type `text/x-component` on the UI · vercel/next.js · Discussion #48527 · GitHub
The suspects involve headers and caching.
When running the server in production mode locally, I do not experience this issue.
