CWL: Bug when using cwltoil (due to overrides?)

Hi, I’m experiencing an issue when running my workflow with cwltoil, though it works in cwltool. The error is: Traceback (most recent call last): File "/Users/mdb/miniconda2/bin/cwltoil", line 11, in <module> sys.exit(main()) File "/Users/mdb/miniconda2/lib/python2.7/site-packages/toil/cwl/cwltoil.py", line 1014, in main options, sys.stdin, None, [], options.job_order) File "/Users/mdb/miniconda2/lib/python2.7/site-packages/cwltool/main.py", line 141, in load_job_order overrides.extend(resolve_overrides(job_order_object, file_uri(job_order_file), tool_file_uri)) File "/Users/mdb/miniconda2/lib/python2.7/site-packages/cwltool/load_tool.py", line 377, in resolve_overrides ret, _ = ovloader.resolve_all(ov, baseurl) File "/Users/mdb/miniconda2/lib/python2.7/site-packages/schema_salad/ref_resolver.py", line 871, in resolve_all val, base_url+subscope, file_base=file_base, checklinks=False) TypeError: can only concatenate list (not "str") to list
