        # wrapping the whole object so n8n sends it as a properly escaped JSON string

        # Hmm, let me reconsider. The "json" mode with jsonBody expects valid JSON.
        # The issue is the expression injects raw text. JSON.stringify wrapping the
        # whole thing as an expression should work.

        # Actually simplest: keep specifyBody=json, but wrap entire object in JSON.stringify
        # n8n will parse the expression result. If expression returns a string (from JSON.stringify),
        # n8n's json mode should send it as-is.
        #
        # But wait - the error says "JSON parameter needs to be valid JSON"
        # This means n8n validates the jsonBody template BEFORE expression evaluation.
        # The raw transcript chars break the JSON template structure.
        #
        # Real fix: use specifyBody = "json" but build the body using n8n's
        # built-in JSON key-value pairs, not a raw string. Or use a Code node.
        #
        # Cleanest approach: Insert a Set node before this one that builds the prompt
        # text safely, then reference it. But that changes workflow structure.
        #
        # Simplest working fix: keep raw JSON mode but use JSON.stringify on the
        # transcript portion only, and use proper escaping.

        # Let me just do it right:
