@Russ Thank you, that worked! Had no idea that option was there. I couldn't find it in the documentation for IFTTT - might make sense to add it?
I also had to add double quotes in the IFTTT config around description, otherwise bash would drop everything after & when spawning the command.
Hi,
I'm trying out an integration where I want to pass the description of a matching calendar event to a local script, so it can parse it for an obsidian URL to open.
in IFTTT, I ask the applet to just pass the Description as a parameter.
The activity log shows this error: Action failure message: Illegal characters in parameters
The description is:
open obsidian://open?vault=main&file=4%20Archives%2FPKB%2FPeople
So lots of potential for illegal characters there 
Is there a way to ask IFTTT to encode the description in a way that TriggerCMD will accept?
