I tried for this existing RPM: https://koji.rpmfusion.org/koji/rpminfo?rpmID=916478 to run this simple script: --------------- [{'type': 0, 'version': '', 'flags': 0, 'name': 'cargo'}, ... name': 'zerotier-one-debugsource'}] {} --------------- Is there a reason the getRPMHeaders() method returns empty {} on every RPM (or at least every RPM I tried) ?
