AWS API Authorization Header - 401 HTTP Response

Hi Folks,

I am trying to get status info about my EC2 instances using the AWS API in uipath. I am using a HTTP Request Activity, and building authorization header as suggested by the AWS documentation. But I am receiving a 401 (Authentication Failed Response) . Has anyone faced this issue before?
Please help me debug this issue.

Thanks,
rav

Can you show how you have set headers? Where did you pass the authorization token etc?
