The activity that throws this error has a property called Orchestrator folder path. If you leave it empty, it will take the default folder (the one you have selected in the bottom right of your Studio, the blue bar at the bottom).
To fix this error, all you have to do is make sure that you have specified the correct path to the Asset as it is in Orchestrator.

then befor the asset add assign var = NameYourOfAsset
