ChatGPT step hit an "User Message" (user_message) is missing" error

Hi everyone, 

I am running a zap with 2 apps, ChatGPT (4.1) and LeadConnector. I have encountered an error, saying that “This ChatGPT (OpenAI) step hit an error: Required field "User Message" (user_message) is missing.” I am pretty new to Zapier and I’m not sure with what I am doing. May I have some steps on how to troubleshoot/fix this error, please? Thank you

Hi ​@Gabriel J 

Make sure all required fields have a value.
