Start with the PutObjectRequest example and the stack trace, then inspect TransformRequestBodyInterceptor.java, CommonUtil.java, and DefaultAsyncClient.putObject. Reproduce the async putObject call with the shown request and trace how its body is transformed. Done means the reported request no longer throws the map/object conversion exception and the behavior is covered by an appropriate test.
