Getting an error during webpack build while using CSS modules

Question

Error
1 | // extracted by mini-css-extract-plugin
2 | export default {"lala":"hQupzgS9tEJmjp6wWbAk"};

(lala is classname)

CSS modules is working fine and changes are reflecting during development but build is failing. I tried updating packages.

      }
    ]
  },

    ]
  }
})

I have tried many different things but not able to resolve this error.
