`Bus 'pcie.3' not found` - where does the bus argument come from?

When starting a VM I am getting the error `Bus 'pcie.3' not found`, which seems to be coming from the bus part of the command:

Code: 
kvm: -device virtio-scsi-pci,id=virtioscsi0,bus=pcie.3,addr=0x1,iothread=iothread-virtioscsi0: Bus 'pcie.3' not found

What can/where can I change that bus argument?

or rather where is it coming from and why would I be getting this error?
 
Proxmox (or QEMU) creates virtual PCIe busses for the virtual devices. If they don't match then maybe your system is not fully up to date with some parts being old and others new. Oor you've selected a machine version that cannot handle the new VirtIO SCSI Single settings, which could be a bug in Proxmox for not checking or not working. Please share the output of pveversion -v and your VM configuration file (qm config ).

That does not look healthy. Kernel verion 6.1 has nog been getting updates (since version 6.2 came available) and has known security flaws. Please upgrade to the latest PVE 7.4.
