Gatsby site couldn't be build

I have struggle with building gatsby site. When I enter to my console 'gatsby develop', my app starts. But when I try build, I see errors like below. Anyone knows how to resolve this? SCREENSHOT

I tried reinstall dependencies, reproduce, use yarn and npm, build in gatsby-cloud, netlify and console, delete node-modules and package-lock.json

Solution

  • I resolved this problem. I changed line img={post.featuredImage || photo} to img={post?.featuredImage || photo}. Line of code needed Optional Chaining. Later I had same error and I changed GatsbyImage component to Image component by ChakraUI.
