test failed, not sure why

Hi,
I am having problems passing test 107 with my implementation and do not understand what is wrong. The File object for file `a` should be what is expected, still cwltest complains. Any ideas?

```bash
Test [107/197] Test if a writable input directory is recursively copied and writable
Test 107 failed: /go/bin/awe-cwl-submitter-wrapper.sh --outdir=/tmp/tmp2k39bljr --quiet v1.0/recursive-input-directory.cwl v1.0/recursive-input-directory.yml
