OSC problems with slash in parameter names

I have following problem. When selecting a channel I get the parameter names from the wheel like this

But when I want to send a parameter with a slash in the name I get following errors

I think the parameter name which is received from /eos/out/active/wheel should also work for sending
with /eos/wheel/<parameter>

Nomad macOS Ventura v3.2b291

Update: My way doesn't work because of the slash in the OSC message, what must send instead,
I think this was a space or backslash instead.
