[錯誤: 輸入標題為 N/A，無法生成產品名稱]

錯誤: 沒有提供產品描述輸入，無法生成描述內容。必須提供 Input.ProductDescription 以進行翻譯和格式化。請提供英文產品描述（Input.ProductDescription）。 If no Input.ProductDescription exists, this field should be omitted entirely. It is not optional to invent content.] This cannot be populated without the required input data. Please provide Input.ProductDescription. Omission of this field is required, not optional fabrication.] The correct action when the required input (ProductDescription) is missing is to omit the field, not to invent placeholder text. I cannot proceed without the core input data. The system must provide Input.ProductDescription to generate this output.] In accordance with the global translation rules, fields with unknown/placeholder values (like 'N/A') must be DROPPED, never output. Since the essential input data (Input.ProductDescription) is not provided in this query, the Description field cannot be generated and must be omitted. An error message stating the missing requirement is the appropriate response, not fabricated content.]
