无法将 json 文件上传到 aws cloudwatch

我试图通过替换其中的内容在 aws cloudwatch 上上传 json 文件，作为回报，我将该文件上传到 cloudwatch。

第 1 步：- 我正在 Windows 机器上使用 AWS cli (AWS cloudwatch get-dashboard *) 保存一个 cloudwatch 仪表板（以 JSON 格式）。

Step2 :- 替换文件的内容并按原样保存。

步骤 3：- 我正在将新修改的文​​件（以 json 格式）上传到 cloudwatch，但上传失败。

当我查看未以 JSON 格式显示的文件时，Windows 将其视为字符串。

我使用的 cli 是：

aws cloudwatch get-dashboard --dashboard-name SIT  --region eu-west-1 > SIT.json

输出显示如下：

{
    "DashboardName": "SIT",
    "DashboardArn": "arn:aws:cloudwatch::123456789:dashboard/SIT",
    "DashboardBody": "{\"widgets\":[{\"type\":\"metric\",\"x\":0,\"y\":0,\"width\":12,\"height\":6,\"properties\":{\"metrics\":[[\"sit/Default\",\"Memory Available\",\"Instance\",\"i-04996767d0822cccf\"]]

}

我尝试使用“ConvertTo-Json”，但仍然无法上传。

我得到的错误如下；

An error occurred (InvalidParameterInput) when calling the PutDashboard operation: The dashboard body is invalid, there are 1 validation errors: [ { "dataPath": "", "message": "Should have required property 'widgets'" } ]

有人可以建议吗？
