@Russ_Thomas

Does this happen on every test execution ?

Russ_Thomas · October 31, 2020, 12:15pm

yes. …

ThanhTo · October 31, 2020, 3:51pm

Is this on Chrome also ? I forgot to mention that Time Capsule is available for Chrome browser currently. If it’s on Chrome I’d need more information.

anon46315158 · October 31, 2020, 4:21pm

I bet is not on Chrome browser.
As far as i know @Russ_Thomas he is firefox addicted.
However it is still a valid issue even in this case (lack of documentation, unhandled exceptions and so on)

Russ_Thomas · October 31, 2020, 6:34pm

No - I get different issues on Chrome but I’m not so concerned about that at this moment (Like @anon46315158 said - I’m a FF guy).

FYI: Chrome complains about something to do with geckodriver (weird) right at the end of the test. But don’t get distracted by that - it might be me doing something stupid (likely).

The id #katalon_only-element is intriguing - I hope Katalon is not injecting stuff into the AUT (there’s enough to keep track of without that kind of thing to have worry about).

I also see this issue happening on chrome.
katalonVersion = 7.8.0.208
os = Windows 10 64bit

For me it happens consistently in an @BeforeTestCase where I execute a public static void logInAs(WebDriver driver, String authUser, String baseUrl, String appUrl, String language)
and specifically when I use the command driver.get(myAuthenticationUrlVariable)

It doesn’t fail my test case luckily, it just pollutes the logs. I cannot recall seeing this before 7.8.0.

Hello there, I have the same error on Katalon 7.8.1 whereas on 7.7 same test works perfectly fine.

WebUI.openBrowser(’’) -> goes fine

WebUI.navigateToUrl(my URL) -> navigates to expected URL but then stays there and does nothing, I have to manually kill the run, and I find this in console:
2020-12-29 08:51:51.176 ERROR c.k.k.c.w.d.KatalonSmartEventListener - no such element: Unable to locate element: {“method”:“css selector”,“selector”:"#katalon_only_element"}
(Session info: chrome=87.0.4280.88)

Too bad I cannot use 7.8 new feature and I am stuck with 7.7 for now. Is 7.8 really working fine?

ThanhTo · December 29, 2020, 8:38am

@yann.sautreuil.ext

We have released 7.8.2 which allows users to disable Time Capsule, can you try it out to see if that resolves the issue ?

yann.sautreuil.ext · December 29, 2020, 10:40am

I just downloaded and used 7.8.2 and ran my test successfully, without updating any setting time capsule or else. 7.8.2 seems to solve this issue for me at least, thanks.

joost.degeyndt · January 4, 2021, 8:27am

I can confirm v.7.8.2 also solved my issue from above. Thank you very much Katalon team!
