Hello Nico,
Take a look at my picture
I have UiPath Studio 2021.4.3 and I Use Salesforce Extension Package last version 1.0.0.872
I don’t modify the package for more than 1 year and a half and I will never modify them again.
Please tell me your version of UiPath Studio and component.
That stuff is just designed incompatibility the function is working you can put the values on properties example ObjectName.
Thanks,
Cristian
