How can I compare faces using AWS Rekognition?

Hi everyone,
Can you please tell me “How to compare faces (one image is in my local system and others are in AWS s3 bucket) ?
I used compare face of AWS Rekognition activity, but there is showing an error Compare Faces: Failed to download file: UiPath.Amazon.Rekognition.Models.Face..

Can anyone please share if you use AWS Rekognition activities?

And also how to pass target url of s3 bucket Object in Compare faces activity?
