Summary
ErrorPolicyUnhandledApplicationException when running cli commands on windows

Steps to reproduce
Steps to reproduce the behavior:

1. start node on windows using cardano-node.exe run --topology ./testnet-topology.json --database-path ./state --port 3001 --config ./testnet-config.json --socket-path \\.\pipe\cardano-node
2. wait for the node to sync and get the tip using the bellow commands:

set CARDANO_NODE_SOCKET_PATH=\\.\pipe\cardano-node
cardano-cli.exe shelley query tip --testnet-magic 1097911063 

3. Check the logs

←[31m[DESKTOP-:cardano.node.LocalErrorPolicy:Error:51]←[0m [2020-08-20 07:06:30.54 UTC] [String "ErrorPolicyUnhandledApplicationException (MuxError (MuxIOException withIODataPtr (readHandle): resource vanished (The pipe has been ended.)) \"(readHandle errored)\")",String "ErrorPolicyTrace",String "LocalAddress {getFilePath = \"\\\\\\\\.\\\\pipe\\\\cardano-node\"}"]

Expected behavior
No errors should be seen.

System info (please complete the following information):

This has been reported to the team

hi @dorin100 @kevinhammond is this still relevant, does it happen consistently or random?

[dcoutts]

I think the complaint here is not that the command fails, but that the node logs reports the successful disconnection of the client as an unhandled mux error.

ErrorPolicyUnhandledApplicationException
  (MuxError (MuxIOException withIODataPtr (readHandle):
  resource vanished (The pipe has been ended.)) \"(readHandle errored)\")

The mux error types should not be classified as an unhandled exception.

[coot]

I believe this will be solved by the p2p node we are working in the networking team. There we classifies errors better: each exception either kills the node or just brings connection down, there's no third option (unhandled exceptions). We will still need to tune logging.

These error messages are still displayed in all logs on my different servers (Windows 10; current version) in the Daedalus Mainnet Software v3.3.2 #16919. It is interesting that this message always appears after the information "Switched to a fork, new tip:". I leave everything else to you programmer of the source code, maybe this info will be helpful for you.

This error message ALWAYS appears and only at this point after the information "switched to a fork...".

Greetings.

[coot]

Thanks for reporting. As I mentioned, this will be fixed with p2p release.

[Plamen5kov]

hey @coot thank you for the help,
I'm having the same issues, I was just wandering what is a p2p release and do you have any idea on when that release is coming or where I could follow the progress of it?

[coot]

You can follow progress on the p2p here.
