Get AWS regions", Error: JAVASCRIPT_CODE_FAILURE: java.util.NoSuchElementException: No value present

 
 
It means discovery is not able to retrieve the AWS regions due to not enough privilege's provided to the IAM account. also check the aws credentials and test it when creating discovery schedule. 
 
Also check the AWS setup provided by servicenow
https://docs.servicenow.com/bundle/sandiego-it-operations-management/page/product/it-operations-mana...
 
Hope its helpful

Anshu

I am not using credentials. We have configured as mentioned in below link:

https://docs.servicenow.com/bundle/sandiego-it-operations-management/page/product/it-operations-management/task/aws-trusted-credential-less.html

We are able to validate the connection while creating cloud discovery.
