无法从 Salesforce 流 http 标注（测试版）访问数组内的数组

Question

在沙箱中，我尝试从 https://data.nasdaq.com/api/v3/datasets/USTREASURY/YIELD.json

收集信息

我使用了直接从流程中创建 HTTP 标注的测试版功能。它根据您提供的示例响应创建外部服务。

我的问题是，在创建的 JSON 中，数组中有数组；因为反应就像

"data":[["2023-02-02","4.62","4.65","4.66","4.76","4.64","4.09","3.75","3.49","3.44","3.4","3.67","3.55"]],

当我从流程中的标注访问响应时，数组 column_names 可用，但数组数据不可用。

创建的 JSON 是：

{"openapi":"3.0.1",
 "info":{"title":"dataNasdaqGetRates"
         ,"description":""},
 "paths":{"":{"get":{"description":"",
                     "operationId":"getRates",
                     "parameters":[{"name":"api_key","in":"query","required":true,"allowEmptyValue":false,
                                    "schema":{"type":"string"}},
                                   {"name":"order","in":"query","required":true,"allowEmptyValue":false,
                                    "schema":{"type":"string"}},
                                   {"name":"limit","in":"query","required":true,"allowEmptyValue":false,
                                     "schema":{"type":"integer","format":"int32"}}],
                     "responses":{"2XX":{"description":"",

                                                                                                                         "start_date":{"type":"string"},

                                                                                                                        }}}}}}}}}}}}

我尝试调整 JSON 以删除嵌套数组，希望它能正常工作。我尝试向嵌套数组添加额外的“type”：（从技术上讲，第一项是字符串，其余是整数）。

我期望在columnx5fnames之后列出另一个名为“data”的顶点定义列表；甚至只是一个文本集合或任何我可以添加到变量和访问的东西。

您将需要创建一个 APEX 定义的集合变量，然后使用赋值元素分配 HTTP Callout 操作的输出。
