Gatsby Failed Deployment to Netlify: Failed to validate error { ValidationError: child "error" fails because ["error" must be an object]

Question

I am trying to deploy a Gatsby site (backend is Contenful) but get the following error from Netlify deployment logs. I can't make sense of the error hence unable to pinpoint where the error is coming from?

The issue occurs only during deployment. The site is working fine in development. I have checked my env variables on Netlify and they are set correctly.

Anyone came across such a cryptic error message before and has managed to resolve it? Appreciate any pointers. Thanks

Answer 1

The crux of the error lies here

Error: Can\'t resolve \'../components/Head\

because netlify filesystem is case sensitive, i should have imported as ../components/head instead of ../components/Head

once that has been resolved, the deployment works!
