@ManjunathanRajan you probably want to provide more details so the maintainers can reproduce your problem and diagnose it. Unfortunately, 'I tried the steps', isn't specific enough no is 'unable to start rackup', nor the scenario that you are describing as 'event Subscription request url'.

Since a 500 is a server error, it means there's an exception message you're not sharing. 9 times out of 10, the exception message tells you where the problem is and what it is.

Without sharing that info, best guess is that you did something wrong.
