Unable to provision vm in vmware esxi 6.7 using vsphere-iso builder

[allaboutopensource]

i am getting an error "vsphere-iso: Waiting for IP...
2020/04/08 12:11:00 packer-builder-vsphere-iso plugin: [INFO] Waiting for IP, up to total timeout: 30m0s, settle timeout: 5s"

during the packer_log=1 debugging i see that there is a line says:

2020/04/08 12:10:31 packer-builder-vsphere-iso plugin: Creating CD-ROM on controller '&{{{} 200 0xc0006be700 0 } 0 []}' with iso '[datastore] ISO/CentOS-7-x86_64-DVD-1908.iso'

while i am getting this error, if i check my vcenter i can see that the vm spins using the image but if i check the cd/dvd drive1 it shows disconnected i.e there is no iso mounted on the vm during the error.

my json file:

I think you are missing floppy definition, take a look here:
