No_more_retries channel_closed_while_in_flight

team we are also getting this error what might be the reason for this issue? could you please help us on this
couchbase.core.OperationCancellationException: QueryRequest, Reason: NO_MORE_RETRIES (CHANNEL_CLOSED_WHILE_IN_FLIGHT)

It means that after a request was sent and while the SDK was waiting for a response, the network connection (channel) became disconnected. It could be that the query node process exited, or a firewall disconnected the connection, or the connection was otherwise broken.

You could see this if you had a very long running query and after not seeing any traffic on the connection for a long time, something (firewall maybe) decided the connection was idle and closed it.
