Question about proper syntax for using Apple Shortcuts to call an input_boolean

I am experimenting with an NFC tag to alter a HA automation through an input boolean. I am able to get a successful result by scanning the tag though it requires me to click on the pop-up on my phone to open HA and run the script.

I watched a video where JuanMTech describes using iOS shortcuts to avoid the extra click. I’m stymied by the syntax and getting an error (“could not run call…” can’t read any more). Can someone take a quick look at this and tell me where I’ve gone wrong?
