Still not working even reverting back to 46 didn’t work. So it may be one of those errors that are caused by upstream. Expo 45 build fail on Android with EAS - #3 by ksi9302. Since this was my play around experiment I didn’t have a proper older lock file to revert to (since I don’t normally use expo web for work)
Anyway what I found so far is that the version of webpack that gets installed is actually not the correct one, it loads 5 rather than 4.x. To mitigate that I had to add webpack as a devDependency on the app so the root node_modules would load up the correct one.
