I’m getting this error now when I try to publish an agent. I duplicated an existing agent to create this new one. I verified that the JSON is valid.

Agent ID: agent\_4a3be12dc0771df957178e96c5. Is there anything else I should try before building it again from scratch?

Mine just published. Significantly reduced costs on this agent - roughly 60-70% with new update. Thank you!
