basename is not recognized in JS evaluation of directory

The Directory specification requires a basename attribute but this is currently being evaluated as a null object by cwlexec since it is not included in the fields.

The attached shows a simple example of attempting to evaluate a basename of a directory where all required fields except basename are included so cwlexec fails:
