InvalidParameterException while confirming SNS notification using Java spring cloud aws

Like Bill says, need to configure the region. Here's some sample code:

return AmazonSNSClientBuilder.standard()
        .withRegion(Regions.US_WEST_2)
        .build();

This was fixed. Issue was with the region configuration. For Spring aws cloud we have to disable auto detection of region and need to configure the desired one.
