Please let me know what is the issue here, thanks

npm run build produces the same error as well.

taha-me commented 3 years ago

So, I found the reason for the first issue here... when adding a new row to feature-rows-group on the home page of the Strapi backend, there should a value in the "text" field.

If not, Strapi will send "null" and Vercel app will break at the build process.

The solution is that Strapi backend should make this field mandatory, or adjust Next.js app to deal with empty "text" field.

Hey @taha-me, do you think the field that should be required would be this one?
