1)
From Discovery > ECC Queue, search for Input probes related to the AWS discovery schedule (e.g., AWS - EC2 Instance).
Check the raw payload in the Payload field to see if the location/region information is being returned by AWS.
If the location data is not present, the issue might be with AWS permissions or API configuration.
2)
Go to System Import Sets > Transform Maps and locate the transform map for AWS EC2 data.
Ensure the mapping for location or region is correctly configured to populate the relevant field in the CMDB
3)
Check Discovery logs
Check the level and short message in your system for this activity to understand where the issue is coming while running .
