Have you tried using the bridge?

[divyanshu013]

This error is thrown by babel while parsing the rc file so bridge won't help. There is some progress going in the next branch https://github.com/umidbekkarimov/babel-plugin-direct-import/tree/next. I think https://github.com/ant-design/babel-plugin-import could also work. Need to see which one works when I've more time.
