VNETs, phpIPAM and PowerDNS - errors about DNS zones creating subnet

I'm trying to understand how to use an external IPAM and DNS integration, to assign IPs to VMs and have them registered in the DNS. I'm trying phpIPAM because Netbox looks to be a far larger and more complex solution. Uisng Proxmox 8.3.3.

I have installed PowerDNS 4.9.3 and phpIPAM 1.7.3, the latest stable available. Both configured to use a MySQL backend. I have also integrated phpIPAM itself with PowerDNS, and the integration looks to work - when I create a domain in phpIPAM it does appear in PowerDNS.

I have created a Zone (VLAN type), and assigned to it the phpIPAM server, and the PowerDNS server for both the forward and reverse DNS zones, and assigned a domain (test.internal) to it. The domain is already created in phpIPAM/PowerDNS.

Next, I create a VNET in such zone, and then tried to create a subnet (using the CGNAT subnet 100.64.0.0/10) and a range within it. This lead to errors. The subnet is actually created in phpIPAM, but the creation returns errors it can't find the forward or reverse zones (i.e. "test.internal", or "0.64.100.in-addr.arpa").

create sdn subnet object failed: can't read zone cyberrange.internal: Invalid response from server: 404 Not Found (500)

Maybe Proxomox handles itself both phpIMAP and PowerDNS, thereby I should remove their direct integration? It's not clear from the documenation. Also, since these operations are managed at the clusert levels, in which logs can I find more details about the encountered errors?
