I am working on a React JS project where I have used ActionHero as a server.
On the localhost, everything is working fine, but when I tried to build the project locally I go this error message.

vishal@vishal-pc:~/projects/x1-platform$ yarn run build

yarn run v1.12.3

There are a lot of solutions given on the StackOverflow for this problem, but none of them are working for me.

I tried deactivating the Uglify plugin but that too is not working.
