如何解决R-POST命令 curl :: curl_fetch_memoryurl，handle = handle中的错误：传输关闭，剩余未完成的读取数据
以下httr POST命令出现问题
try(POST("https://marketsgateway.pjm.com/marketsgateway/xml/query",add_headers(.headers = headers),body=uptoXML,verbose()),silent=FALSE)
它返回此消息：
Error in curl::curl_fetch_memory(url,handle = handle) :
transfer closed with outstanding read data remaining
似乎我需要以某种方式更改POST设置以获取所有数据。当请求的是较小的数据集时，它可以正常工作。但是，当它稍大一些时，我会收到此内存错误。我已经搜索了R解决方案，但是找不到如何修改POST默认值来获取所有数据块的方法。
以下是详细输出（更改了敏感的cookie数据）：
