I published a process and it has three input arguments: two with type string and one with type string array. Input arguments are shown correctly in Orchestrator, e.g. in package explorer and process settings:
However, when I try to run process via Assistant, only string types of arguments are shown:
I have not crossed checked the behaviour, but one thing I always forget is to update the package in the process within the orchestrator folder. May be this is the case?
You may have updated and published the package, but could it be that the process in question is not updated to the newest package (where you have input array argument?). This way the assistant only shows you two arguments (from previous version of your package) and not three (your newest version of the package)?
