AWS Rekognition validation error while adding faces to collection

Question

Hi ,  
  
I am trying to add the faces to the collection  
  
 var params = {  
    CollectionId: "aws:rekognition:us-east-1:xxxx:collection/collectionidnewbatch",   
    DetectionAttributes: \[  
    ],   
    ExternalImageId: "testphotoid",   
    Image: {  
     S3Object: {  
      Bucket: "parentbucket/nested/bucket",  
      Name: "ab1"  
     }  
    }  
   };  
   rekognition.indexFaces(params, function(err, data) {  
     if (err) console.log(err, err.stack); // an error occurred  
     else     console.log(data);   
   });  
  
and getting following error  
   
"image.s3Object.bucket' failed to satisfy constraint: Member must satisfy regular expression pattern: \[0-9A-Za-z\.\-_]

Answer

Hi,  
  
From the code snippet, it looks like the issue is that you are not specifying the bucket and name correctly. It should probably be:  
  
Bucket: "parentbucket",  
Name: "nested/bucket/ab1"  
  
The S3 bucket needs to be the actual bucket name. Path details are part of the object name, not the bucket name.  
  
There's example code in https://docs.aws.amazon.com/rekognition/latest/dg/add-faces-to-collection-procedure.html if that's helpful.  
  
Hope this helps,
