Python ga：browserVersion 段过滤器发出 HttpError：400 以使用不排除用户段.我正在使用 Google Analytics Reporting API V4

我一直在编写一个Python脚本，为YTD的特定视图提取GA数据.在这段时间里，我有一个机器人流量，它在视图中被过滤掉了，但在4月22日仍然有一个很好的流量块.我想使用一个段过滤器和ga:BrowServerVersion，并排除该流量.不幸的是，我遇到了以下错误:

&lt；HttpError 400在请求https://analyticsreporting.googleapis.com/v4/reports:batchGet?alt=json时返回"接收到无效的JSON有效负载.未知名称"not"at"report\u requests[0].segments[0].dynamic\u segment.user\u segment.segment\u filters[0].simple\u segment.or\u filters\u for\u segment.segment\u filter\u子句[0].dimension\u filter:找不到字段."，"description":接收到无效的JSON有效负载."report\u requests[0].segments[0].dynamic\u segment.user\u segment.segment\u filters[0].simple\u segment.或segment\u filters\u for\u segment.segment\u filter\u子句[0]的未知名称"not".维度过滤器:找不到字段."&gt；

以下是相关代码:
