Not really @LazyBean , still with the problem.
I’ve downgraded the version of UiPath Package , UiPath.imageProcessing to 23.4.0 and in this way I made the robot work.
Also, if the code doesn’t appear in the tab, in Projects => Setting. Activate or deactivate the “Modern Desing Experience” can be helpful.
The error message still appearing in some robots, but they work.
