      Hello everybody,

      I'm writing a service thask that read some input (a process variable mapped on a data Input) and write results on the same process variable.

      Here is the mapping:

      DataInputSet: input-file-uri-list:String,ouput-root-folder-uri:String

      DataOutputSet: success:Boolean,remapped-input-file-uri-list:String,remapped-ouput-root-folder-uri:String

      Assignments: inputFileUriList->input-file-uri-list,ouputRootFolderUri->ouput-root-folder-uri,success->success,remapped-input-file-uri-list->inputFileUriList,remapped-ouput-root-folder-uri->ouputRootFolderUri

       

      Here is node source:

      The process is successfully validated, but when I run It I get the error reported below.

       

      Can anyone help me?
