Vercel : NextJS 13 Error on fetching SSG data – Reactjs

I have a application in NextJS 13 and deploy it on Vercel.
I’m generating all content from Localess integration.

Locally the SSG is working properly. with : npm run build and npm run dev
When I’m deploying the application to Vercel I’m receiving the next error in the building logs :
