I have been with InterSystems for 20 years (including my year as an intern) and I am currently in charge of the Application Services team. Application Services is focused on creating and enhancing inhouse applications within InterSystems (both based on InterSystems IRIS as well as a select number of commercial platforms).
in the screenshot above you are trying to run the class in the FILERO Namespace. Did you try running that command in FILEROIRIS?
@Alexandra Mirzac - welcome to the Community :) I would suggest the following:
1) Make sure you have saved and compiled your class, and that it returned with no errors.
2) Make sure when you are testing in Terminal you are connected to the correct Instance and the correct Namespace
3) Double-check spelling and case in your Terminal command compared to your compiled classname
Please try those things out and let us know if that moves you forward.
From your initial screenshot:
Perhaps you need to be on the 'filerodev2023' Instance, rather than the 'IRIS' instance and you show above on your HOME4 node?
