Katalon Object Spy strange error "invalid argument"


I’m trying out Katalon on a new device and I’m trying to use Object spy. First of all the “Object spy” does not take me to the address I set. Chrome just opens up and shows “data;” on the search bar.
If I type in the URL that I actually want to use, I will immediately be prompted for my username and password (which is normal) and then I get the following error after a few seconds:


If I click OK on the error and login with my user and pwd I am able to go to the URL but the object spy is not working. I don’t see the black bar on the top of the page and I basically can’t use any functions from “object spy”.

Any feedback is much appreciated. Thanks in advance.
