proxmoxer.core.ResourceException: 500 Internal Server Error: unable to find configuration file for VM 100 on node 'pve'

I am new to proxmox and to the Proxmoxer Python API. I got some examples of using the Proxmoxer api from its use in the Ansbile playbook.

In my python program, I am able to run all the 'get' API calls using the Proxmoxer Python library, like
print(proxmox.access.users.get()). that works, so the login creds all work.

However, when I call the API to do a full clone, I get a cryptic error:

proxmoxer.core.ResourceException: 500 Internal Server Error: unable to find configuration file for VM 100 on node 'pve'

Here is the snippet of my code:
proxmox = ProxmoxAPI(target, user=user, password=password, verify_ssl=False)
vmname="foobar"
pve_node = "pve"
clone_id = "9001" # vmid of my Ubuntu2204 Linux Template
proxmox_node = proxmox.nodes(pve_node)

arg list

post_data = {
"vmid": proxmox.cluster.nextid.get(),
"node": pve_node,
"name": vmname,
"newid": clone_id
}
taskid = proxmox_node.qemu(post_data['vmid']).clone.post(**post_data) # i tried calling .create(**post_data) too, same error message

I get the above error.

I logged into PVE and created a dummy file "touch /etc/pve/qemu-server/100.conf" to see if a config file should be created ahead of creating a VM. However, i got an error that "configuration file for VM 101" was missing. So thats not the issue.

I am not able to find any logs on Proxmox /var/log or journalctl -f , about any other debug info when I run my script.

Any tips?

You're trying to post to the new id, which does not exist at this point. You need to post to the template id.

Try something like

post_data = {
    "newid": proxmox.cluster.nextid.get(),
    "name": vmname,
}

taskid = proxmox_node.qemu(clone_id).clone.post(**post_data)

thank you! I realized that I had interchanged the newid & clone id values in the API call. found out using the Postman API tool! :)
