• lg driver: webos@0.3.0
• chromedriver: 2.36

The log shows an error where your client script is sending commands to a nonexisten session. Also, your code doesn't make sense: where is targetElement defined? Finally, I'm not sure Chromedriver 2.36 is new enough to support per element screenshots.

[Jiyvn]

@jlipps sorry, targetElement is a placeholder, actual locator is //button[@class="button-base medium button-contained MenuButton undefined"], and element id should be 0.6263299632119397-1 according to the error message provided above

[jlipps]

Sure, that's fine. My other two points remain relevant however.

@jlipps tried chromedriver 2.37-2.46, unfortunately, no one can work. Can't even start session with 2.39~2.46
