Refer to common01\readme.md for the initial registry set up and should have been completed prior to this exercise. copy the folders Errors and middlewares from the folder auth\auth22\src and paste it to common02\src. modify the index.ts to import all the files that were pasted into common02\src and export them immediately for other services to reuse it.
