amazon-web-services - StepFunctions.getExecutionHistory 节点 Lambda 上的 AWS 开发工具包出错，“资源类型在此上下文中无效：stateMachine”

Question

我正在使用 Node env lambda 中的 AWS 开发工具包；我试图在调用启动之前获取执行历史记录以检查正在运行的状态机。

所以我已经导入了SDK，可以启动状态机了

const AWS = require('aws-sdk');
const StepFunctions = new AWS.StepFunctions();

const startParams = {
  stateMachineArn: 'STATE MACHINE ARN',
  input: JSON.stringify({}),
};

StepFunctions.startExecution(startParams, (error, data) => {
  if (error) {
    console.log(
      'THERE WAS AN ERROR STARTING THE STATE MACHINE. DETAILS IN THE FOLLOWING LOG'
    );
    console.log({ error });
  } else {
    console.log('Step function triggered successfully.');
    console.log({ data });
  }
});

控制台输出

Step function triggered successfully.

但是，当我尝试使用相同的 ARN检索状态机执行历史记录时，结果如下。

const AWS = require('aws-sdk');
const StepFunctions = new AWS.StepFunctions();

const retrieveParams = {
  executionArn: 'STATE MACHINE ARN',
  maxResults: 10,
  reverseOrder: true,
};

StepFunctions.getExecutionHistory(retrieveParams, (error, data) => {
  if (error) {
    console.log(
      'THERE WAS AN ERROR RETRIEVING EXECUTION HISTORY. DETAILS IN THE FOLLOWING LOG'
    );
    console.log({ error });
  } else {
    console.log('Execution history retrieved successfully.');
    console.log({ data });
  }
});

控制台输出 1

THERE WAS AN ERROR RETRIEVING EXECUTION HISTORY. DETAILS IN THE FOLLOWING LOG

控制台输出 2
