I am facing any issue in react. Here How I am defining the class BackendServiceClient

class BackendServiceClient {
  private readonly source: string;

constructor(source?: string) {
    if (source) {
      this.source = source;
    }
    axios.defaults.headers = this.setDefaultHeaders();
  }
}
.... some logic

export default BackendServiceClient;

This how the BackendServiceClient is export in index.ts in common library in this class we export all the vars that could be used by clients of the library

export { default as BackendServiceClient} from './api/BackendServiceClient';

While building this commons library into my application I got error commons.BackendServiceClient is not constructor

and when checked the line causing errors from file in node modules

backendServiceClient: /*#__PURE__*/new commons.BackendServiceClient(),

Does someone have faced this issue ? Thanks
