在 Coinbase-Advanced REST API 上工作。获取市场交易中的响应代码 404，需要修复

问：

使用此获取市场交易功能，我得到此响应。我正在尝试进入市场交易。我做错了什么？它不是我的 API 密钥或标志，因为我在其他功能中使用那些没有问题，它不是 TS，它不是标头

`Response Code: 404
Response Data: b'{"error":"NOT_FOUND","error_details":"ProductID \\"product_id\\" could not be found.","message":"ProductID \\"product_id\\" could not be found."}'
