Unhandled Exception: PlatformException(evaluateJavaScript_failed, Failed evaluating JavaScript ... )

[robin7331]

Hey there!

This package seemed to look pretty cool so I gave it a shot.
Unfortunately I get this error under iOS (haven't tested Android yet) when I hit the play button.

19:22:03.079 282 info flutter.tools [VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: PlatformException(evaluateJavaScript_failed, Failed evaluating JavaScript, JavaScript string was: 'player.cueVideoById("secret-but-correct-video-id", 0)'

19:22:03.079 283 info flutter.tools Error Domain=WKErrorDomain Code=5 "JavaScript execution returned a result of an unsupported type" UserInfo={NSLocalizedDescription=JavaScript execution returned a result of an unsupported type})

I did run pod install and also flutter clean. The video thumbnail is showing up in my view so I guess thats at least a partial success.

I am facing same error :

Thanks for reporting issue 😊 . The plugin is completely tested on Android only. Performing tests on iOS currently. Will push new version after tests complete, before this weekend.

Have the same issue, works great on android but on iOS I get the exception:

Unhandled Exception: PlatformException(evaluateJavaScript_failed, Failed evaluating JavaScript, JavaScript string was: 'player.playVideo()'
Error Domain=WKErrorDomain Code=2 "The Web Content process was terminated" UserInfo={NSLocalizedDescription=The Web Content process was terminated})

Tested new Version 1.1.0 on iOS device and it works as intended, but in simulator video starts playing only after 4-5 minutes (although the above mentioned error shows up) in my case.
Can you guys check whether or not it is working on real iOS device as well as simulator.

@sarbagyastha Still getting the same exception on iPhone 6s. Running 12.1.4

Hello,

@sarbagyastha Still getting the same exception too on iPhone 8. Running 12.1.2

[janvandenberg]

Hi @sarbagyastha I've tested v1.1.0 on both a iOS 11 and 12 simulators (iPhone X, iPhone 8 etc) and a physical device (iPhone X) and it doesn't seem to be fixed.

I did manage to see a playing video on an iOS 11 simulator at one time, but only after 4-5 minutes like you described. When I restarted the simulator I got the error again:

[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: PlatformException(evaluateJavaScript_failed, Failed evaluating JavaScript, JavaScript string was: 'player.playVideo()'
Error Domain=WKErrorDomain Code=5 "JavaScript execution returned a result of an unsupported type" UserInfo={NSLocalizedDescription=JavaScript execution returned a result of an unsupported type})

[sarbagyastha]

Done a little bit of debugging with Safari Web inspector, seems like the issue might be due to XHR ads related files. Will have to rewrite the iOS part i guess, so will take some time. If someone finds out workaround then a PR will be much appreciated. 😊

You're using older version of dart.. run flutter upgrade and the issue should be fixed.
Note: Set notation was only introduced in Dart 2.1.2 for Flutter.

[pmrajani]

@sarbagyastha it's works now thank you.

@sarbagyastha Hello how about that problem? I am waiting your upgrade.

Any update?

[dmazlum]

@abeeriqbal there is no update. I changed my player to webview. I embeded youtube code in webview. This is temporary solution. cheers

[sandyara]

Any Update ?

[silentsonata]

This bug is affecting me also. Love the plugin though!

[sarbagyastha]

Sorry folks, due to lack of spare time I couldn't work on the issue. I will work on it from next weekend onwards.

[sarbagyastha]

The issue is finally fixed and will be updating the plugin tonight. It's working on iOS now.

@sarbagyastha I had the same issue. In my case, when value.isReady is still false, I got an error. So, I modified to display the indicator and wait until isReady changes.
It might be better to show progress indicator until isReady changes true.

[sarbagyastha]

@frgmt Done in Version 6.0.0

" Unhandled Exception: PlatformException(FWFEvaluateJavaScriptError, Failed evaluating JavaScript., Instance of 'NSError', null) "
