Cloudformation 中的 Cloudwatch 仪表板错误

如何解决Cloudformation 中的 Cloudwatch 仪表板错误

我正在尝试使用 cloudformation 中的 JSON 在 AWS 系统管理器中创建 cloudwatch 仪表板。我有一个模板，其中有几个 lambda 函数已经在堆栈中运行。我更新如下：

{
"AWstemplateFormatVersion": "2010-09-09","Description": "The AWS CloudFormation template for deployment. Version 1.0","Mappings": {
  "SourceCode": {
    "General": {
      "S3Bucket": "solutions","KeyPrefix": "connected-solution/latest"
    }
  }
},"Resources": {
  "dashboard": {
    "Type": "AWS::CloudWatch::Dashboard","Properties": {
      "DashboardName": "Dynamodb-LambdaDashboard-xxx","DashboardBody": {
        "widgets": [
          {
            "type": "metric","x": 0,"y": 0,"width": 12,"height": 7,"properties": {
              "metrics": [
                [
                  "AWS/DynamoDB","UserErrors"
                ]
              ],"view": "timeSeries","stacked": false,"period": 300,"stat": "Sum","region": "us-east-1"
            }
          }
        ]
      }
    }
  }
}

}

当我尝试更新堆栈时出现以下错误：

Property validation failure: [Value of property {/DashboardBody} does not match type {String}]

请指教。如果有任何问题，请告诉我 谢谢，

解决方法

DashboardBody 应该是 string，而不是 json 对象。您必须字符串化（将 json 对象转换为字符串）您的 DashboardBody。例如：

{
"AWSTemplateFormatVersion": "2010-09-09","Description": "The AWS CloudFormation template for deployment. Version 1.0","Mappings": {
  "SourceCode": {
    "General": {
      "S3Bucket": "solutions","KeyPrefix": "connected-solution/latest"
    }
  }
},"Resources": {
  "dashboard": {
    "Type": "AWS::CloudWatch::Dashboard","Properties": {
      "DashboardName": "Dynamodb-LambdaDashboard-xxx","DashboardBody": "{\"widgets\":[{\"type\":\"metric\",\"x\":0,\"y\":0,\"width\":12,\"height\":7,\"properties\":{\"metrics\":[[\"AWS/DynamoDB\",\"UserErrors\"]],\"view\":\"timeSeries\",\"stacked\":false,\"period\":300,\"stat\":\"Sum\",\"region\":\"us-east-1\"}}]}"
    }
  }
}
