我的 camunda fetchAndLock API 请求有什么问题。获取 InvalidRequestException

Question

我有 2 个主题可以从 API 接收数据，我可以通过代码成功执行这些主题。现在我正在尝试使用邮递员工具通过 rest api 执行。现在我收到 InvalidRequestException。在尝试请求之前，我使用 camunda get external-task api 获取外部任务，我的主题显示 there.Later 我尝试使用 /external-task/fetchAndLock API 发送输入变量。

外部任务响应是：

http://localhost:8080/engine-rest/external-task

        "activityInstanceId": "Activity_0jokenq:0623e6f2-4837-11ec-8c7e-02426d005d3a",

我的要求是：

POST http://localhost:8080/engine-rest/external-task/fetchAndLock
    {
        "workerId": 1,
        "maxTasks": 100,
        "topics": [
            {
                "topicName": "testingtopic",
                "lockDuration": 100000,
                "variables": {
                    "a": {
                        "value": 1,
                        "type": "long"
                    },
                    "b": {
                        "value": 2,
                        "type": "long"
                    },
                    "id": {
                        "value": 1,
                        "type": "long"
                    }
                }
            }
        ],
        "asyncResponseTimeout": 5
    }

抱歉，我在请求正文中错误地提到了错误。我提到

"variables": {}

但是是json"variables": []

的数组

我这里提到的只是变量名"variables": ["a","b","id"]

后来我用POST /external-task/{id}/complete请求传值完成了流程
