Probably because in JS, var style = window.getComputedStyle(node); returned null.
@sdanes1 could you provide some more information about this? Is it reproducible and deterministic (happens every time)? Could you verify whether it is browser/os specific or specific to a website? If the latter, is the website accessible somehow (e.g. as a html file)?
As this can have several causes, we need some way to reproduce it in order to verify a fix...
@roesslerj See answers below:
- Is it reproducible and deterministic (happens every time)? Yes.
-Could you verify whether it is browser/os specific or specific to a website? I originally ran on chrome. Testing it on firefox it gives a slightly different exception, org.openqa.selenium.JavascriptException: TypeError: parentStyle is null, but at the exact same place.
I did a little more testing and it does seem to be a problem with the .check call on my app as I was able to get the newest recheck-web to work with google but using the older selenium 3.8.1 version. I have attached a copy of the page in question as a zip file
dashboard.zip
Let me know if this helps or you need more info
Hmm. I can check that website without errors, so it seems to be related to OS/Browser ... let me think about it.
Hmm. I will rely on your expertise. I appreciate all your help! We really would like to use recheck-web in our testing if we can iron out these issues. Are you running with the 3.8.1 version of Selenium? Also I was executing in Saucelabs cloud, I tried running locally and eliminating saucelabs and still get exception:

That's great! If it occurs with saucelabs, we can most probably reproduce it. Can you give us the capabilities with which it occurred. Like:
capabilities.setCapability("browserName", "Safari");
capabilities.setCapability("platform", "macOS 10.13");
capabilities.setCapability("version", "11.1");
Sure.
screenResolution=1600x1200
For chrome;
platform=Windows 10
version=74.0
For firefox:
platform=Windows 10
version=67.0
We were able to reproduce it and create a fix. Since we meanwhile released recheck-web 1.5.0, this will be a hotfix (1.5.1) ... could you verify whether this fix works for you?
Hotfix beta now available (also on Maven Central): https://github.com/retest/recheck-web/releases/tag/v1.5.1-beta.1
Once you verified that this works for you, we'll release a hotfix version. Thanks!
Just finished test with 1.5.1-beta.1 works like a charm! Thanks so much guys!
