This isn't a zero Fun
, it's just that the point is outside the default domain of -1 to 1, in which case the function evaluation returns zero. Could you try setting the domain while constructing the space? There are issues with tanh
, but this doesn't seem to be one of them

Ah, of course! I sometime forget where I am when debugging a deep stack trace.
