BadResponseException: Bad JSON
Dear Dropbox Community,
I am using the Dropbox API v2 for my Android app. Lately I have been seeing issues when trying to download a file with client.files().download() where the file does not (yet) exist. Instead of the expected DownloadErrorException, I am getting a BadResponseException (full stack below). I am using the SDK as in compile 'com.dropbox.core:dropbox-core-sdk:2.0.2'
Any ideas?
com.dropbox.core.BadResponseException: Bad JSON: No suitable constructor found for type [simple type, class com.dropbox.core.DbxRequestUtil$ErrorWrapper$ApiErrorResponse<com.dropbox.core.v2.files.DownloadError>]: can not instantiate from JSON object (missing default constructor or creator, or perhaps need to add/enable type information?)
