Trouble trying to use FreeNAS with docker-ddns

OK so I appreciate this project and it fits a need I have to be able to give a FreeNAS server a resolved DNS name on my domain.

So I set up the docker instance and I can test it fine using the provided JSON string.

http://myhost.mydomain.tld:8080/update?secret=changeme&domain=foo&addr=1.2.3.4

That works and a DNS A record is created.

However when I try and set it up from FreeNAS it does not seem to work with the 3 revolvers mentions for standard DynDNS lookups. Namely.

/nic/update
/v2/update
/v3/update

FreeNAS uses inadyn and the config file is such.

    period = 300
    custom customProvider {
    ddns-server = "ns.mydomain.net:8080"
    ddns-path = "/v3/update/"
    ssl = false
    username = "randomuser"
    password = 'SuperSecret'
    hostname = { "myhostname" }
}

However when running the daemon in debug mode I am getting a 404 Error.

What is odd is I am not even getting any logging back from the server.

I am using docker logs --tail 100 -f dyndns and all I am getting is this:

creating zone...
creating zone file...
creating REST api config...
[ ok ] Starting domain name service...: bind9.
2020/06/18 17:01:26 Serving dyndns REST services on 0.0.0.0:8080...

As I say I have tried all 3 variants above but nothing seems to work? Am I missing something here?

Any insights would be appreciated.

Ok replying to myself because I think I have worked it out. The entire string needed passing so the path in the config has to be:

/nic/update?hostname=

Ok not the most intuitive parameter but no fault of dyndns so. Mea Cupla and please just take this as a reference for others.
