6001 - Shaka Error Drm.requested_key_system_config_unavailable () | Edge LIMITED |

player.configure({ drm: { servers: { 'com.widevine.alpha': 'https://license.arthouse.com/widevine', 'com.microsoft.playready': 'https://license.arthouse.com/playready', 'com.apple.fairplay': 'https://license.arthouse.com/fairplay' }, // Tell Shaka to try them in this order advanced: { 'com.widevine.alpha': { distinctiveIdentifierRequired: false }, 'com.microsoft.playready': { distinctiveIdentifierRequired: false } } } }); But that wasn't enough.

One Friday night, she got a frantic call from her boss

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

player.getNetworkingEngine().registerRequestFilter((type, request) => { if (type === shaka.net.NetworkingEngine.RequestType.LICENSE) { // Ensure the correct license server is used per key system if (request.uris[0].includes('widevine') && !window.navigator.requestMediaKeySystemAccess) { request.uris[0] = request.uris[0].replace('widevine', 'playready'); } } }); Finally, she added a user-friendly message for when all DRM systems fail:
