AWS S3删除对象给出未引用属性值错误

Question

通过节点在s3中删除对象时，出现以下错误：

{
  "message": "Unquoted attribute value\nLine: 313\nColumn: 79\nChar: h",
  "code": "XMLParserError",
  "time": "2019-05-22T09:55:35.060Z",
  "originalError": {
    "message": "Unquoted attribute value\nLine: 313\nColumn: 79\nChar: h",
    "code": "XMLParserError",
    "time": "2019-05-22T09:55:35.045Z"
  },
  "statusCode": 400,
  "retryable": false,
  "retryDelay": 30
}

我正在使用以下代码删除对象：

var AWSS3 = new AWS.S3();
let file = 'path/to/file/myfile.json'
        var params = {
            Bucket: bucketName,
            Key: file
        };

        console.log(`Deleting data with key ${params.Key} from bucket ${params.Bucket}`)
       AWSS3.deleteObject(params, function(err, data) {
            if (err) {
                console.error("Unable to delete S3 item. Error JSON:", JSON.stringify(err, null, 2));
            } else {
                console.log("S3 DeleteItem succeeded:", JSON.stringify(data, null, 2));

我想念什么？
