Amazon自动完成脚本问题

Question

以前，我的App Script项目运行完美，但是现在结果是一个空数组。当我在浏览器中使用相同的链接时，答案是正确的。

这是我的相关摘要：

var result = UrlFetchApp.fetch('https://completion.amazon.co.uk/search/complete?search-alias=aps&client=amazon-search-ui&mkt=3&q=cellulite&qs=&cf=1&fb=1&sc=1&',
  {
    'muteHttpExceptions': true,
    'contentType': "jsonp"
  }).getContentText();
Logger.log(result);

哪个产量

[cellulite, [], [], []]

但是，如果我使用browser中的链接，答案是：

[ "cellulite",
  [ "cellulite massager",
    "cellulite cream",
    "cellulite",
    "cellulite brush",
    "cellulite cup",
    "cellulite remover",
    "cellulite massager brush",
    "cellulite oil",
    "cellulite cupping therapy",
    "cellulite brush dry"
  ],
  [ {}, {}, {}, {}, {}, {}, {}, {}, {}, {}],
  [],
  "40N0Y0SNGX6"
]

如果相同的URL可以正常工作，为什么result为空？
