The Fairplay licensing server URL is missing in the provided AppleFairplayDRMConfig.

This error occurs when the Fairplay license server URL (LA_URL) is missing. The license server url can either be provided directly in the LA_URL, or it can provided through the getLicenseServerUrl callback, which is called with the init data of the content and must return the license server url.

Please make sure that the license server url is correctly set.
