The endpoint that I am trying to access is working in postman and sending a response.
Getting this error, while trying to execute REST Connector
The error message indicates that the endpoint could not be reached. Maybe you tried a locally available host from Postman?
Without information about which host you are trying to connect to, it’s difficult to know more.
Hey @oops_aman, could you please share a screenshot of the Input Mappings tab to see the full connector input?
Given the error code is 408, is it possible that the REST Connector call fails with a timeout? In that case, you might need to increase the timeout values in the element template properties.
Thanks for response @kristoffer.jalen @chillleader . I have resolved it, forgot to update here. 
Please share your solution, so others can learn!
