In the example code of a plugin the src/i18n/locales/enObj.tsx is filled with an object. Because I did not required the object i made it undefined but this will throw an exception which crashes the plugin boot.

The code which wil crash the plugin
export const enObj: I18nObjects | undefined = undefined;

Code as work arround

export const enObj: I18nObjects = {
  defaultData: [
  ],
};
