PiSignage Services/API Node TypeError

@tec6/node-red-pisignage-services

I'm having some troubles with this node for controlling pisignage through the API. It was working a couple of weeks ago and after no changes to my setup, it is no longer working. I'm guessing it's a change with the pisignage API. I'm not sure how to tag the maintainers for the node project but maybe someone else will also find this useful to verify their own issue.

Using the examples provided by the pisignage node devs and my own flows now produces a "TypeError: Cannot read properties of undefined (reading '0')". Below is the example flow sans credentials. The TypeError shows up for any interaction with the pisignage node and I can't seem to find much clarity on the cause of a TypeError reading 0.
