I’m trying to do what I’d have expected to be one of the simplest things possible: concatenate the value of a variable with another literal string in a json object.
The problem is that no matter what I try I end up with quotes in places I don’t want them. For example "\"post\"_created". That’s the output from this setup:
I’ve tried concatenating with + between strings, there seems to be no concat function (despite what Claude says).
I’m clearly missing something very obvious since this must be a common use case.
Any guidance appreciated.
