The requests library checks that the headers are either strings or bytes. Currently, the two test_object_expirer tests fail with the message: InvalidHeader: Header value 1487879553 must be of type str or bytes, not <type 'int'> The header in question is "x-delete-at". The patch converts it to a string, before making a Swift Client request. Change-Id: I738697cb6b696f0e346345f75e0069048961f2ff
