I’m writing some scripts for may Homey pro 2023.
I’m trying to analyse the answer to a fetch commnand
And, I struggle with the functions : a lot of them (includes, indexOf …) seems to be unavailable !

Probably, I’m doing Something wrong !!

Thank you for your help

In fact, I tried to apply those functions to an object not of the string type !!
