Reproduction

https://stackblitz.com/edit/github-jdzmbl?file=components/Feed.vue

1. Open stackblitz
2. There are generated .output by npm run generate. I don’t know how to execute the generation command in stackblits, so I generated the files locally and put them in the project. You should get the same result by regenerating.
3. Run npm run preview
4. On / path you should see valid JSON array with content. But on subpath you should see HTML instead JSON

Describe the bug

I have several pages to display the content. In the desktop, the filtered JSON is displayed correctly on each page. However, after generating the site, HTML is returned instead of JSON
