Resolving Some Inputs Missing Error in Clay Prompt Column

❓Problem: Prompt column blocked due to missing inputs – despite fallback logic I'm using a Prompt column in Clay that references fields like First Name, Last Name, and Gender. In the prompt, I clearly defined fallback logic like:

“If no first name is provided, use 'Unknown'. If gender is missing, start with 'Hello' instead of using a gendered salutation.”

Still, I keep getting the error: “Some inputs are missing”, and the prompt doesn’t run at all. What I’ve already tried:

What I want: Let the prompt always run, even if some fields are missing, and allow GPT to handle the fallback logic as written. Question: How can I reliably avoid the “Some inputs missing” error and force the prompt to execute? Thanks in advance dear community 🙏
