MDI Command Error

Hello.
Recently I ran into an issue with adding in a z probe for automatic tool touch off for a newly built CNC using a mesa 7i96s. After running I get an error "halui.mdi-command-00 does not exist". I have attached my config files. The only line in my postgui file is as follows (so I dont have to attach it)

net ztouch halui.mdi-command-00 <= pyvcp.ztouch

Any help would be greatly appreciated. Thank you!
