S3 DeleteObject throwing exception

[ballagas]

Here is my code:

s3_delete_object = Botocore(
    service='s3', 
    operation='DeleteObject',
    region_name='us-east-1'
)

yield gen.Task(s3_delete_object.call,
                Bucket = bucket, 
                Key = relativePath
            )

I enabled botocore debug logging, and here is the trace.

I didn't test it with s3.
Try another library for S3: https://github.com/tornadoweb/tornado/wiki/Links

Did you have any success with resolving this issue with S3? I'm having a similar error with PutObject request.

For async file upload to S3 see: https://gist.github.com/nanvel/c489761a11ec2db184c5
