Recevied a data message for flow, but the flow cannot be found

Hi,all


I find my AppProxyExtension output a log that is 'flow_director_create_io_handle:3170 (0): control: Recevied a data message for flow 3218250285, but the flow cannot be found' in console.app, so ,the completionHandler block was not called after calling '-(void)readDataWithCompletionHandler:' of NEAppProxyTCPFlow.


I have successfully opened the flow.


What does this log mean and how can I solve this problem?


Thanks,

Tt
