为什么谷歌云converse_conversation返回None或空？

Question

我正在使用 Flask 与 google cloud discoveryengine_v1 合作，我正在尝试请求新的对话。

我从文档here获取了示例代码，但在测试时它返回一个类型错误，表明该函数不返回任何内容。

代码如下：

from flask import Flask, jsonify, request
from google.cloud import discoveryengine_v1

@app.route("/new", methods=['POST'])
def new_question():
   api_data = request.get_json()

   answer_response = sample_converse_conversation(api_data['question']) # api_data['question'] is a string

   print(answer_response)
   return answer_response

def sample_converse_conversation(question):
   try:
      # Create a client
      client = discoveryengine_v1.ConversationalSearchServiceClient()

      # Initialize request argument(s)
      request = discoveryengine_v1.ConverseConversationRequest(
        name="<name value>", # removed the value but this has the project details 
      )

      # Make the request
      response = client.converse_conversation(request=request)

      # Handle the response
      return response
   except Exception as e:
      print(e)

以下错误：

为了测试，我使用邮递员来运行 API 请求。

彻底检查文档后，分配给属性名称的值末尾缺少 (-)。

projects/{project_number}/locations/{location_id}/collections/{collection}/dataStores/{data_store_id}/conversations/{conversation_id}. Use projects/{project_number}/locations/{location_id}/collections/{collection}/dataStores/{data_store_id}/conversations/-

如果有人遇到同样的情况就在这里补充一下哈哈！
