Hi Madhawa, I went through your impl and it works great. Try to improve the test cases and documentation (README.md on git) when you get a time.
Furthermore, I have added Event simulator REST API endpoints to the doc that you shared earlier. After getting debugger to work, try to wrap event simulator endpoints as well. You can refer to [1] for the documentation on them. [1] https://docs.wso2.com/display/DAS400/Simulating+Events Regards, Grainier.
