[Sidefx-houdini-list] COPs > File exists / File doesn't exist - Switch

I'm currently trying to get COPs to reliably use a Switch COP
to pass through a second input - if the first (A File COP) can't pull a file off disk.
Although the File COP is putting out a valid black frame under these circumstances,
the Switch COP errors red, if one of it's inputs isn't evaluating properly.
I thought the SwitchCOP example using string-length might help, but neither
that or a pic() evaluation of the image seems to help the nodes problems.
Does anyone have a tried and tested way of doing this?
