Got "NaN" for latency

[Shivakishore14]

I am trying to test a echo websocket written in java.
this is the command that i gave thor --amount 1000 --messages 100 ws://localhost:8085/web-soc/websocketendpoint
(the echo websocket server is working fine)

Result

Thor:                                                  version: 1.0.0

God of Thunder, son of Odin and smasher of WebSockets!

Thou shall:
- Spawn 8 workers.
- Create all the concurrent/parallel connections.
- Smash 1000 connections with the mighty Mjölnir.

The answers you seek shall be yours, once I claim what is mine.

Here latency is NaN, what might be the reason for this issue ?

I am getting the same issue, Latency is NaN. Downgrading fast-stats to 0.0.1 does not seem to help.
Appreciate any help.
