RE: Automating your Mobile Presence with a Telegram Bot

The issue is the quote is being sent in the HTTP request inside the JSON object.

I fixed the script in your bot Chatter to add,

input.toString().replace('"', '\"')
>>
json.messages.add({"role":"user", "content":(conversation.getLast(#input, 1)).input.toString().replace('"', '\"')});

This will fix it for now. We will also update our HTTP code to automatically escape quotes for all JSON objects.
