Hello, I'm trying to tackle the whatsapp business chatbot for customer service. I was able to upload the correct data to a vector database, and everything works correctly up until I reach the last node, the response from WhatsApp, which I can't make it answer to the phone that messaged it. Attached is a photo, which adds the correct phone number but adds an unnecessary 1 which then provides an error. I found multiple people with the same error but no solution, any ideas?
