I am trying to compare two images present in my bucket but no matter which region i select i always get the following error:-

botocore.errorfactory.InvalidS3ObjectException: An error occurred (InvalidS3ObjectException) when calling the CompareFaces operation: Unable to get object metadata from S3. Check object key, region and/or access permissions.

My bucket's region is us-east-1 and I have configured the same in my code. what am I doing wrong?

Answer 1

It happened to me using the AWS rekognition sdk for android , the problem was that the region of the S3 bucket is not the same in my request , so I had to put the correct region in the request (same as S3 bucket ) :

 rekognitionClient.setRegion(Region.getRegion(Regions.US_WEST_1));//replace with your S3 region

Answer 2

I had the same problem. What I did to fix it was to rearrange my bucket and the folders. Make sure that your image is directly in your bucket and not in a folder in your bucket. Also double check that the name of the images are correct and that everything is on point.

Answer 3

Check if the S3 and Image Rekognition is in the same region, I know, it's not nice or documented (I guess), but this guys are talking about it here and here
