API v2 java throwing BadResponseException: Bad JSON for uploadSessionFinishBatchCheck

I'm using the UploadSession feature of the java SDK to upload multiple files at once, and at the end of the process when I call files().uploadSessionFinishBatchCheck, I'm getting an exception:

com.dropbox.core.BadResponseException: Bad JSON: expected field 'success', but was: 'name'
