functions in a Nuxt 3 app

i have a fairy simple site with a registration form and a function endpoint to append rows to a google sheet (a bit complicated the google auth with the cf workers not supporting the googleapis library) but my issue is that the function works locally using "npx wrangler pages dev -- npm run build" but when deployed it seams to not find the route and return the layout site. loaction is /functions/sheetappend.js
