about:1 GET https://www.sathyamolagoda.me/about 404 (Not Found)

I’m having an issue with my website, built with Nuxt 3 and deployed on Vercel. The page at https://www.sathyamolagoda.me/about returns a 404 (Not Found) error when accessed directly, although it works fine when navigating through Nuxt routes. Google and other third-party tools can’t find or access this page. What could be the problem?
