Hi @PadmajaS ,
The configurations you have shared look good. You mentioned rule is not triggering, but in console logs I can see log of the sendEvent action which means the rule was executed and action was also executed. Is the log not for the rule you are facing issues with or do you mean the network call is failing and showing 204 response as per the second log? If it is the case that rule triggers but you get 204 response for the network call, it might be possible that due to redirect the server response wasn't received in time on client side and you get the 204 status code. Can you check if the data is landing in Adobe?
If above is not the case then please share few more details,
1. Do you see rule triggered log in console?
2. Do you get any error in the console?
3. What is shown in the network tab?
Cheers!
