opnsense 26.1.2_5 os-ddclient 1.30 hetzner record update not working #5243
Description
it seems the ddclient hetznerDNS is using the wrong API endpoint when it comes to update an record that is already added. There is:
https://docs.hetzner.cloud/reference/cloud#tag/zone-rrsets/update_zone_rrset
Update an RRSet�Copy link
Updates an RRSet in the Zone.
(this is used by the script)
and there is:
https://docs.hetzner.cloud/reference/cloud#tag/zone-rrset-actions/set_zone_rrset_records
Set Records of an RRSet�Copy link
Overwrites the resource records (RRs) of an existing RRSet in the Zone.
debug log with the current script:

Its obvious I guess, it says cant update record with this endpoint.
I changed the script now to:
def _update_record(self, headers, zone_id, record_name, record_type, address):
"""Update existing record with new address"""
url = f"{self._api_base}/zones/{zone_id}/rrsets/{record_name}/A/actions/set_records"
data = {
'records': [{'value': str(address)}],
#'ttl': int(self.settings.get('ttl', 300))
}
->>I had to comment out the ttl, because it gave "404" from the api and Im not sure how to properly set it.
Now debug log looks like this:

it says "error" but and I can see inside the hetzner api console:
zone.rrset.set_records
System ?
