+Note: The difference is that the `http` method returns more `aggregation_type` fields than the `http v2` method. The `http v2` is enabled by setting `enable_http_server_v2`.

 在导入或者查询时，我们可能遇到这个错误。如果你去对应的 BE 日志中查看，也可能会找到类似错误。
 
-这是一个 RPC 错误，通常由两种可能：1. 对应的 BE 节点宕机。2. rpc 拥塞或其他错误。
+这是一个 RPC 错误，通常有两种可能：1. 对应的 BE 节点宕机。2. rpc 拥塞或其他错误。
 
 如果是 BE 节点宕机，则需要查看具体的宕机原因。这里只讨论 rpc 拥塞的问题。
