          Args:
              kwargs (dict): A dict with a `name: type` item
                  and optionally a `default: value` item, where name is the
                  name (id) of the workflow input (e.g., `dir_in`) and type is
                  the type of the input (e.g., `'Directory'`).
                  The type of input parameter can be learned from
                  `step.inputs(step_name=input_name)`.
  
          Returns:
              inputname
  
          Raises:
              ValueError: No or multiple parameter(s) have been specified.
