Hello @ajitStephen

Thank you for raising the issue

May I know which branch you checked out from?
I suggest to follow the tutorial from part one to make sure all the required steps are followed, currently I dropped the development of the tutorial, being held by the book project on Nest.js which is going to be released very soon
