expected constant BitVector(2 bits, 0xc) but got BitVector(2 bits, 0x0)

Hi - great library, thank you!

Scanning for the same service it always terminates with a variant of this exception (usually does find the service first):

fs2.interop.scodec.CodecError: ansection/2/rdata: expected constant BitVector(2 bits, 0xc) but got BitVector(2 bits, 0x0)
fs2.interop.scodec.CodecError: ansection/0/rdata: expected constant BitVector(2 bits, 0xc) but got BitVector(2 bits, 0x0)
fs2.interop.scodec.CodecError: qdsection/0/qname: expected constant BitVector(2 bits, 0xc) but got BitVector(2 bits, 0x0)

so in various sections of the responses - any idea why? Is there some unusual case not being handled?

Thanks!
Peter

Just some additional information, I've tried constraining the scan interface to my primary (wifi in this case) interface but no change.

Here's the scan output before it fails:

Instance(Service(lutron,tcp,local),Lutron Status._lutron._tcp.local,22,Lutron-05719a97.local,HashMap(FW_STATUS -> 1:NoUpdate, CLAIM_STATUS -> Claimed, ST_STATUS -> good, DEVCLASS -> 081B0101, NW_STATUS -> InternetWorking, CODEVER -> 23.06.24f000, SYSTYPE -> RadioRa3Processor, MACADDR -> xxx, SERNUM -> xxx),List(/192.168.100.172, /fe80:0:0:0:3aab:41ff:fe83:c4e6, /fda7:fe01:357a:4676:3aab:41ff:fe83:c4e6, /fd49:4044:8744:1:3aab:41ff:fe83:c4e6))

Here's dns-sd output:

Which of the dns-sd commands is equivalent to the PTR question the scan() ?
