@Aleksei @mykola-mokhnach It is an important topic.Please note 3 issues are present in 3 TV’s of LG.
Drivers are able to launch the app in TV with the Desired capabilities,But to inspect the app i am not able to launch in appium inspetor the 3 error mentioned above.
Let me know if full logs are needed.
@wreed

appium-lg-webos-driver is not maintained by Appium team. Try asking about your issue at some dedicated forums from LG.

4

Did you install lg sdk?
Also from lg sdk it looks like it works in emulator of WebOs

@Aleksei Yes i installed the LG SDK.

I am able to launch the application in TV’s.But to inspect the app its not launching in inspector and shows below error.

@Aleksei Please expedite this issue ,Its blocking to us to proceed further.
We need to test the app in real devices, emulator is not helpful for us,so we barely use it

7

we are not LG Appium driver developers :slight_smile:
but can only advice something e.g. can you inspect app with chome? https://webostv.developer.lge.com/develop/getting-started/app-debugging

8

@Aleksei Thanks its resolved now.

9

@Raja_Subudhi Please post the resolution so that other users of LG TV’s can benefit. That’s the whole point of this forum.

10

Sure @wreed Below is the solution.

WebOS for LG tv uses very old chrome drivers.We need to use the additional capability “chromedriverExecutable”: “driver exe path” to invoke the appp in inspector.

By using the driver https://chromedriver.storage.googleapis.com/index.html?path=2.36/ i am able to resolve the same.
