I am working on this workflow that pulls information from LinkedIn jobs and then curate a personal email to send using instantly. Everything is working except for the very last node that is supposed to send to Instantly. I am so close but I am totally at a loss as to why my Instantly node is not working. I have verified API key and Campaign IDs are both correct and been trying to troubleshoot in circles with LLM! Please look at the attached screenshots; perhaps it's a simple thing I am overlooking? I appreciate anybody’s insight as I’ve been racking my brain trying to figure it out. The error says:
