I am using antlr4 with javacript target since years, Now it is throwing error when i do a build using webpack

Module not found: Error: Can't resolve 'fs' in '/Users/Saravanan/projects/frontend/widgets/web/node_modules/antlr4'

It was working fine with webpack-4 with following settings enabled. But now with wbpack-5 it is throwing the error as above.
