Problem: trying to set up a workflow that will automatically respond to leads via instantly. Getting stuck on teh last node where instantly sends all the info to the api for it to actually send the message. I’m sure there are other errors but i have been stuck here all day and about to go postal.
Have gotten multiple errors, but I believe the gist of it is that the json is not being recognized. I’m trying to pass various fields through teh workflow but i keep getting errors that they’re invalid.

Based on the tone and wording, decide if the lead is interested in booking a call.\n - If the message clearly shows interest or excitement (e.g. "yes", "sounds good", "let’s do it", "send the link", etc.), mark \"interested\": \"YES\"\n - If the message says "no", "not now", "not interested", or sounds like a rejection, mark \"interested\": \"NO\"\n - If the message includes a question but sounds open-minded, treat as \"YES\"\n\n2. Then, write a natural, friendly reply in your own words, as if you’re a human SDR named {{$json.sendingaccountfirstname}}.\n\n - If interested, thank them and drop this link casually: https://calendly.com/stuart-oden\n - If not interested, thank them politely, wish them well, and stop.\n\n3. Format your replies with one sentence per paragraph, two line breaks in between paragraphs. This is for readability.\n\n4.
