@huynguyen Can you please help me, I am encountering same problem.


Hi @patriciasimone.padua,
Do you use the latest version of Katalon Studio?


Already fixed, thank you very much :slight_smile: checked some proxy settings


Hi Team,

How can I request for an invite to use the plugin from my Katalon Studio Account. I would like to use the api key generated to run tests in console mode


Just go to the Katalon store and then the manage options. Can generate an API through there.


I am getting the same like you.
Can you please provide your solution for the same.
Even i lost my 2 days work as well. :frowning:


I am under corporate network, so i configured in the Settings the proxy im using and saved it and tried reloading the plugins again.
Katalon Studio Preferences>Katalon>Proxy


yes, I am up to date


Hi ,

I am getting a similar issue with Applitools plugin.

Please help.

After following these steps, I restarted Katalon and reloaded the plugins the issue was solved for me.
