Failed to compile.

Cannot find "/tsconfig.prod.json" file. Please check webpack and ForkTsCheckerWebpackPlugin configuration. 
Possible errors: 
  - wrong `context` directory in webpack configuration (if `tsconfig` is not set or is a relative path in fork plugin configuration)
  - wrong `tsconfig` path in fork plugin configuration (should be a relative or absolute path)
