setting spigot path doesn´t work

Hi list

I want so set the spigot path to a new location, as stated here:

https://cycling74.com/docs/max5/refpages/jit-ref/spigot~.html

The patcher below gives the error:
spigot_cache: bad path name as spigot_cache

for any path, even the default spigot path.

did I make a mistake or is this a bug?

thanks
