@NUCsimple could you please take a look?

[NUCsimple]

@zroubalik Of course, I'm working on fixing it.

[NUCsimple]

Now it should be OK. I passed the local test. Can you help me test again? @zroubalik

[zroubalik]

@NUCsimple I am ready to help you, how can I do that and where did you do the change?

[NUCsimple]

@zroubalik I just upgraded the image. You don't need to make any changes. You just need to trigger the test again.

[zroubalik]

@NUCsimple great, seems like the test is stable now. Thanks.

Could you please add the test image sources to this directory https://github.com/kedacore/test-tools/tree/master/e2e/images ?

Thanks!

[NUCsimple]

@zroubalik Okay, I'll add this image later.
