Vsphere-iso builder if the network name contain a "/" will not find it

Not sure in Packer how can I represent “/” from the name. I get the bellow error when I am tying to build a template using packer.

error creating vm: network ‘VLAN_105-’ not found

In terraform I fix it by using the ASCII %2f instead of “/”

EX: VLAN_105- in terraform looks like this VLAN_105-
