Getting Invalid dSYM file

I uploaded the dSYM file for my iOS app by dragging it to the dSYM Center upload area. After it completes the upload, it says the dSYM is invalid. And it does show up in the list of files. When I generate an error, I don't get the appropriate information as a result. The first upload of the dSYM file worked and then when I updated my app and tried to upload the latest dSYM, i now get this error.

I was able to use the sidekick application to get past this issue. Using the App I was able to upload the latest dSYM successfully.
