I'm performing validation on a captured phone number using AI created code and get the following error: [ReferenceError, sendMessage is not defined] code: const number = event.payload.text if (number.length === 9 && /^\d+$/.test(number)) { workflow.mobileNumber = number } else { await sendMessage("Please enter a 9-digit number.") } Isn't sendMessage a pre-defined botpress function?

You can't send messages via code (at least not within botpress). Better to save the message you want to a variable then display that. If you don't, you'll have parts of your conversation in the visual flow editor and others outside, which is going to be confusing.

ok. got it. Thanks.
