We have been trying deploying a React-Admin demo app but we ran into a serious of problems. We managed to solve the errors related to the build, but the deploy is still not successful, because it seems that the publish folder is not correct. We tried with the root folder and with build folder. With the root the deploy is successful, but then it does not get proxied to the right folder (https://stellular-mooncake-de67c7.netlify.app/). With build, it escapes because it cannot find the build folder. Running mkdir build before the build solves this problem but the app is still not deployed in the right folder because we still get a 404.
Both yarn and npm gave the same problem, we are running out of ideas. Can anybody help? Thank you in advance.
