I’m trying to send a dynamic prompt to OpenAI’s Chat Completions API using the API Connector. I’m using the JSON body method with a dynamic value, and I’ve removed all other top-level parameters. However, when I click “Reinitialize call,” the popup window to enter a test value for the message parameter never appears. Instead, a message parameter is auto-generated, and I can’t edit it. As a result, my API call always uses the static test value or fails entirely. How can I properly pass a dynamic input to the API in the JSON body?
