[dnsdist] Spoof SVCB with SpoofSVCAction

[Daniel Stirnimann]

Hi all,

I run dnsdist 1.7.0 with RPMs provided by PowerDNS.

I'm trying to use SVCRecordParameters with SpoofSVCAction as described
in the documentation at
https://dnsdist.org/reference/svc.html#newSVCRecordParameters

However, the example in the documentation is not working for me.

dnsdist -c
> local svc = {newSVCRecordParameters(1, "dot.powerdns.com.", {
alpn={"dot"}, port=853, ipv4hint={"192.0.2.1"}, ipv6hint={"2001:db8::1"} })}
> addAction(AndRule{QTypeRule(64), QNameRule('_dns.resolver.arpa.')},
SpoofSVCAction(svc))
Error: [string "return addAction(AndRule{QTypeRule(64), QName..."]:1:
Unable to convert parameter from userdata to
St6vectorISt4pairIi19SVCRecordParametersESaIS2_EE
stack traceback:
	[C]: in function 'SpoofSVCAction'
	[string "return addAction(AndRule{QTypeRule(64), QName..."]:1: in main
chunk>


Any hints why this fails?

Thank you,
Daniel
