1. I use: generator-jhipster: "7.9.3" webpack: "5.74.0" webpack-bundle-analyzer: "4.6.1" OS: windows 10
2. It's compile successfull on dev, but not on prod.

IT's seem like a webpack problem, i got this trace in the end of the stack trace: (webapp build prod) on project guineeinfo: Failed to run task: 'npm run webapp:prod' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1) -> [Help 1]

If you have these errors, verify if in your tsconfig.json you have "target": "es2020", "module": "es2020" if so, change to "target": "es6", "module": "esnext".
