Hi @lukasc, I’ve tested this with the help of @ahan and it looks like that the API is working in the latest version of the products. Since we were not sure what you meant by “returning blank” we tried a few different things.
If opensession is called without assigning to anything, then nothing is printed in the prompt for sure, but mode is opened in the background; if app=opensession(“mode”), then the expected behaviour is that mode opens, and variable “app” can be used for future calls to evalremote(app,"…"), but “app” does not appear in the script workspace.
We next tried clearing the PATH variable so that none of our products is there, and then app=opensession no longer worked! So we are guessing that maybe when you upgraded your OS, you did not follow the KB instructions that you had mentioned earlier?
Please let us know if you believe that is the case.
