I am using AWS SDK iOS v 2.5.0 to upload/download files to S3. I would like to use acceleration if enabled on the bucket. To test if acceleration is enabled I thought I could do the following, but it fails:

    AWSS3GetBucketAccelerateConfigurationRequest *accReq =   [AWSS3GetBucketAccelerateConfigurationRequest new];
    accReq.bucket=bucket;

    return [[[AWSS3 S3ForKey:region] getBucketAccelerateConfiguration:accReq] continueWithBlock:^id(AWSTask *task) {

        return task;
    }];

The credentialsprovider is properly setup and working for the region. The error message I get is:

PermanentRedirectThe bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.mybucketnamemybucketname.s3-us-west-2.amazonaws.com

I thought from the examples that I did not have to specify endpoint for checking whether the bucket is accelerated or not? Am I doing something wrong in my request? Thanks. T
