I just hit this issue. Fresh maas 3.3.4 installation, booted a few nodes, they all appear as New but cannot commission because of this error "ScriptSet matching query does not exist.".
If I try "Test" instead of "Commission", same error. But if I try "Rescue", then it works (powercyles, boots into rescue image, makes itself available for ssh).
