test in question is CwlToolsTestCase.test_index1. We're expecting a single dataset as dataset_value , but getting a list here.

I suppose this worked at one point, since it was in the PR description

Secondary files are supported at least partially, see the index1 and showindex1 CWL tools created to verify this as well as the test_index1 test case.

might be a recent change on the Galaxy side
