We have a problem only when we test the app in a real device. we get this error trying ro reproduce a content with DRM: "Got Shaka Player Error: Unable to find object." This error is displayed after load the url. The network filter is not reached and the error is displayed before.

We dont received another message and this is all we have.

We think that the error is generating shaka version from widevine: ../configure --ios --cpu arm64 --release --eme-impl ~/libs/widevine_prebuilt_cdm/shaka_plugin/release_cdm.json

This output is displayed after creating shaka-player version:

Please reply to or close your other issues. If this is the result of fixing those issues, you should post this as a comment instead of opening a new issue. New issues should be for completely different problems.

Can you post your source code or give some more info on how you're interacting with the API? Can you post runtime logs? Compile logs aren't useful for debugging runtime problems.

We are able to check just this ShakaPlayerError from console:

Error Domain=ShakaPlayerErrorDomain Code=0 "Unable to find object." UserInfo={NSLocalizedDescription=Unable to find object., ShakaPlayerErrorSeverityKey=0, ShakaPlayerErrorCategoryKey=0}

And this is the source code that we are using:

class PlayerViewController: BaseViewController, UIGestureRecognizerDelegate { var playerView: ShakaPlayerView? var player: ShakaPlayer?

override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(true)

guard let shakaPlayer = try? ShakaPlayer() else {
    print("Error creating player")
    return
}

self.player = shakaPlayer
self.player?.add(self)
self.player?.client = self
let shakaPlayerView = ShakaPlayerView(player: self.player)
shakaPlayerView.frame = self.view.bounds
self.playerView = shakaPlayerView
self.containerPlayerView.addSubview(self.playerView!)

self.configureAndLoadAssetWithAutoplay()

}

func configureAndLoadAssetWithAutoplay(startTime: Double = 0.0) { var urlMedia = getMediaUrl() var license = getLicense()

self.player?.configure("drm.servers.com\\.widevine\\.alpha", with: license)

self.player?.logLevel = ShakaPlayerLogLevel.V2
self.player?.load(urlMedia,
                  withStartTime: startTime,
                  andBlock: { error in
                    if let error = error {
                        print("Error loading manifest: \(error.message)")
                    } else {
                        self.player?.currentTime = 0
                        self.player?.play()
                    }
                  })

}

}

extension PlayerViewController: ShakaPlayerClient { func onPlayer(_ player: ShakaPlayer, bufferingChange is_buffering: Bool) { if (is_buffering) { self.loadingIndicator.isHidden = false self.loadingIndicator.startAnimating() } else { self.loadingIndicator.isHidden = true self.loadingIndicator.stopAnimating() } }

func onPlayer(_ player: ShakaPlayer, error: ShakaPlayerError) { self.displayAlertAndExit(title: "Shaka Player Error", message: error.message) }

}

extension PlayerViewController: ShakaPlayerNetworkFilter { func stringArrayToData(stringArray: [String]) -> Data? { return try? JSONSerialization.data(withJSONObject: stringArray, options: []) } func onPlayer(_ player: ShakaPlayer, networkRequest request: ShakaPlayerRequest, of type: ShakaPlayerRequestType, with block: @escaping ShakaPlayerAsyncBlock) { if (type == ShakaPlayerRequestType.license) { request.headers[Globals.PlayerKeys.KEY_ACCESS_TOKEN] = token request.headers[Globals.PlayerKeys.KEY_DEVICE_ID] = xtvupdevice request.headers[Globals.PlayerKeys.KEY_EVENT_ID] = eventId // This cert.bin is the widevine from widevine if let data: Data = getFile(forResource: "cert", withExtension: "bin") { request.body = data } } block(nil) } func onPlayer(_ player: ShakaPlayer, networkResponse response: ShakaPlayerResponse, of type: ShakaPlayerRequestType, with block: @escaping ShakaPlayerAsyncBlock) { block(nil) }

}

I faced the same error - directly on launch. In my case it has been caused by setting the logLevel directly after creating the player. shakaPlayer?.logLevel = .none

Maybe this raises the error in the release-version!? Removing it seems to fix it in my case...
