I am currently seeing this error when building my branch. I am using create-react-app behind the scenes. I used to see the same issue on my local, but clearing the node_modules directory and running yarn again fixed it. Unfortunately I am unable to do the same on the netlify environment. I tried upgrading my package.json version but that did not work. Can someone please look into it? Thanks!
