Does your test execution continue?

I belieive this is only a warning. I have also seen it in my logs but havenā€™t noticed it did anything.

3

Yes, the error is just a warning. We will look for a way to resolve it in future releases. For now, it is safe to ignore it.

Hi! I think itā€™s just a warning. Doesnā€™t cause any error on my side. Iā€™m also getting that on my console at the beginning when I run my scripts.

Hi,
TNX for your comments.
After that error, my test execution start and crushed, every time in different location of the test.
so you all said that my crushed in not as a result of this error?

7

No, it should not. Donā€™t hesitate to start a new topic with the execution logs- weā€™re happy to help.

8

OK,
Thank you very much, Iā€™ll do it

Use old version. katalon 5.5 version is not gave this error. I think katalon new update is not work correctly. If you have katalon old version you can test your project properly.

Hi,

Iā€™m pretty new to automation and Katalon Studio tool, please bear with me.

Iā€™ve been receiving this error when Iā€™m attempted to create BDD test via this video tutorial:

And I receive this error:

Anyone have any ideas why this is? Any help would be greatly appreciated.

Hi, as above, it is just a warning, I also have the same showing in console but after fixing the errors shown after it there were no more issues. Ignore it and focus on the errors below that first and see what happens. If what you have posted is your entire console output I donā€™t actually see the issue?

12

Well, reading above responses, even if that error is warning, could we get ticket to resolve that ?
For someone new to Katalon, the error might confuse them.
Also, if we have a workaround of same, we can share it in broader forum as well

Is issue mentioned above fixed in latest release i.e. Katalon 6.2

14

I ran my tests yesterday a few times with no issue and then I upgraded ( 6.2.1) .and now I am getting the exact error as stated above. Is there a fix for this issue??

15

Just the fact that this topic has 2.8k hit tells the tail of the story: It is bothering and confusing for a lot of people!!

Getting same error in 6.2.1 katalon version :
SLF4J: The requested version 1.7.16 by your slf4j binding is not compatible with [1.6]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.

This warning also presents in version 6.3.0.

Katalon team, please focus on core functionality and resolving longstanding issues such as this. Iā€™ve noticed documentation lagging more and more. Every official release breaks something . A dark theme taking precedence over the many outstanding issues is something I will never understand. Pushing a plugins marketplace by self-cannibalizing takes away existing functionality, and puts in its place a can of worms for the already-frustrated community to open. You are only alienating the user base by enforcing your new revenue stream. Many aspects of Katalon Studio are brilliant, however Iā€™m not seeing progress where it counts. The current state of things makes it clear Katalon is not reliable enough for use in the enterprise.

Hi @ryan.gaelick,

Thanks for your feedback, we will consider to remove this warning in the next release.
Starting in v6.3.0, we will focus on KS performance, and UI/UX experiences improvement.
We will publish new API docs for v6.3.0 soon.

Thanks.
