Hi @ajith-ramawickramagm

I have pulled a new instance of the course that seems to work fine now. It is the course-introductory-workshop course and I have renamed your old instance to be course-introductory-workshop1.

Can you let me know if this works okay for you? Thanks!

Hi @ajith-ramawickramagm
