Hi Angelica - Can you share a little more about what you're trying to do? Are you using the database or assistant? Or even share your workflow json so I can take a closer look? You can DM me that if you'd like.
Also, if you are using Assistant, I've been working on a new n8n node to make using Assistant easier and will be sharing more about it in the coming weeks. Happy to give you early access if you'd like to try it.
