Google Actions Builder 需要许多插槽

问题描述

大家好，我需要一些帮助/了解所需的插槽填充是如何工作的。

查看文档内部： https://developers.google.com/assistant/conversational/scenes

我可以添加尽可能多的必需插槽，但是当我尝试在 Google Actions Builder Simulator（测试）中对其进行测试时，当我只填充一个插槽时出现此错误：

{
  "insertId": "---","jsonPayload": {
    "timestamp": "2021-06-22T11:46:48.872626Z","endConversation": {},"status": {

    },"executionState": {

          },"level": {
            "status": "EMPTY","mode": "required"
          }
        }
      }
    }
  },"resource": {

    }
  },"timestamp": "2021-06-22T11:46:48.872626Z","severity": "CRITICAL","labels": {
    "channel": "preview"
  },"logName": "---","trace": "---","receiveTimestamp": "2021-06-22T11:46:48.912102599Z"
}

对于某些上下文，我使用了两个必需的插槽填充：

解决方法

您可以根据需要包含任意数量的必需插槽。填满所有必需的插槽后，scene.slots.status 将设置为 "FINAL"，并且将满足预先填充的条件。

对于每个插槽，您可以通过选择 This slot is required 将其标记为需要。如果您需要访问该值，可以通过选择 Customize slot value writeback 并为会话参数键提供名称将其写入会话参数。

您收到的错误是 "There is no prompt message nor helper instruction in the response."。

在配置每个插槽时，您可以为首次提示用户填充插槽时添加自定义提示（取决于插槽类型）。如果未配置，您将收到上述错误消息。

要添加提示，请在槽配置下，选择 Send prompt 并添加您想对用户说的话。

例如：

candidates:
  - first_simple:
      variants:
        - speech: What is your favorite number?
