The next morning, Maya documented the incident for her team:

The configuration was too rigid. The player was a locksmith showing up with only a titanium key, but the lock was made of brass. She dug into the Shaka Player configuration file, where a previous developer had hardcoded:

player.configure({ drm: { servers: { 'com.widevine.alpha': 'https://license.arthouse.com/widevine' } } }); The problem? The manifest file for Cybernetic Vampire III (and several other 4K remasters) contained multiple DRM schemes. But the player was asking for Widevine. When Widevine wasn't available (or the license server was down for that key system), Shaka threw the REQUESTED_KEY_SYSTEM_CONFIG_UNAVAILABLE error because it had no fallback.
