External IPAM now fails with "mac address cannot be nil" on Compute Resource deployment.
I had successfully integrated phpipam with the new external ipam plugin however, since I upgraded to Foreman 2.3.1 I have noticed that "create host" now shows an error under the interfaces tab even though I am using a vmware compute resource and the mac dialog box is greyed out...
"ERF12-9889 [ProxyAPI::ProxyException]: Unable to retrieve the next available IP for subnet 184.108.40.206/24 External IPAM. ([RuntimeError]: mac address cannot be nil) for proxy https://foreman-proxy:8443/ipam" (values have been changed obviously)
If I change "Deploy On" to "Bare Metal" and and add a fake mac address I get a next_ip, then I can change it back to vmware and I can provision from a template again.
This is not ideal for other people less familiar with Foreman than me.
Not sure if it is related or not, but the IPAM Dashboard has also stopped working, now showing an error...
"ERF12-5974 [ProxyAPI::ProxyException]: Unable to obtain groups from External IPAM. ([TypeError]: no implicit conversion of String into Integer) for proxy https://foreman-proxy:8443/ipam"
I was able to see a list of subnets before.
No changes to the phpipam version or api user have been made since this was working, in fact I actually see a 200 in the phpipam apache log for the Dashboard request.

Please let me know if you require any additional information.

unfortunately even in debug logging mode the log shows nothing more than the actual displayed messages I already listed (surrounded by a bunch of cache statements), there is no ruby stacktrace per se as this seems like an intentional validation error. If you think there is some hidden info I can provide them but they will be lengthy.

I already looked at the proxy.log in debug mode and there were no entries for the in initial "mac address cannot be nil" when first selecting "Create Host" I believe that comes from /usr/share/foreman/lib/proxy_api/external_ipam.rb which is part of the main foreman code.
rpm -qf /usr/share/foreman/lib/proxy_api/external_ipam.rb
I verified that there was no communication with the proxy at this time by running a tcpdump on port 8443. I see traffic when I select "Bare Metal" and add a fake mac address but nothing when the vmware compute resource is selected and I click on the Interfaces tab.

I downloaded the external_ipam.rb from your PR to test and the error changed but still produces, "Oops, we're sorry but something went wrong no implicit conversion of String into Integer", I have attached the stacktrace for you.

Mark - I have found the issue and opened a PR. I'm unable to properly test this as I do not have access to any VMWare resources, however I'm fairly certain that this is the cause. Just need to remove one line of code.
Basically, foreman is raising an Exception if the mac address is nil, which it should not be doing.
Let me know if this resolves the issue. My apologies for any inconvenience here!

it appears that smart_proxy_ipam plugin is now passing back an error that a mac address is needed.
ERF12-9889 [ProxyAPI::ProxyException]: Unable to retrieve the next available IP for subnet 10.60.25.0/24 External IPAM. ([RestClient::BadRequest]: 400 Bad Request) for proxy https://foreman-proxy:8443/ipam
This seems to be coming from smart_proxy_ipam-0.1.3/lib/smart_proxy_ipam/ipam_api.rb
I saw in the PR you mentioned that the proxy will use a unique ID if the mac is not present for the IP cache key.
I checked and there does not appear to be an updated version available if this fix also requires a newer plugin. Currently smart_proxy_ipam (0.1.3)
Do I need to wait for the release of Foreman 2.3.2?
