The error is weird because it typically occurs when Webpack <5 is used without adding the required Babel plugins which handles the modern Javascript syntax. However we are using the react-scripts v5 which also use Webpack v5 which can handle modern syntax out of the box.

I can't reproduce the issue.

• Which npm version are you using?
• Are you on the latest state of the repository?
• Is the repository clean?

1. forgot to give npm version that I am using is npm@9.7.2
2. yes, I was using git clone https://github.com/eclipsesource/jsonforms-react-seed.git of master branch.
3. I will give a try in a new folder.

Thanks a lot, trying in a new folder, it works well. closed. The issue comes up while npm audit fix --force executed, since the webpack version is downgraded to

"name": "webpack",
"version": "4.19.1",
