Hi there,

Katalon Studio earlier versions are not working as well just for your clarifications, I’ve checked all earlier versions such as 4.5, 4.6. 4.7 and so on even in 5.0, all of them pronounce the same error like your attached picture.

The main reason due to Kobiton update its API and we will have to adjust it accordingly. This require many efforts to fix and we have been awared of it, so please wait for it to be fixed asap.


Hi Vinh,

Thanks for your prompt response :slight_smile: . Even I have checked this with the earlier versions. Yes, you are right I am getting the same error. But, I am wondering what it had worked for me with 4.8 version, and I had developed few scripts with Kabiton.

However, I will wait for it to fix.

This has been fixed in Katalon Studio 5.2. So feel free to grab it and try again.

Hi, Thanks for letting me know. I have tried it and happy to see that it works fine now.
