"Invalid key format" error description

To help with the integration for creating Fairplay Streaming enabled content, I would like to know the exact details of following error if possible:

(AVPlayer)

-12642 "CoreMediaErrorDomain" "#EXT-X-KEY: invalid KEYFORMAT "com.apple.streamingkeydelivery"" -


Since no license request was done towards the KMS, I assume that the manifest is okay, but the content itself differs from correctly protected content.

Can I myself get more infomation from the device in such an error case?

I too am having this issue. Not sure what's causing the issue as "com.apple.streamingkeydelivery" seems to be the documented correct key.
