Issue with Variable Substitution in API Request Node

Hello,

I’m currently using conversation nodes to extract variables and pass them into an API Request node. However, instead of receiving the actual values, the API request is receiving the variable placeholders as literal strings (e.g., {{CustomerName}}).

This setup used to work correctly, so I’m unsure what has changed. Could you please help me identify what might be causing this issue?

Thank you!
