Gatling recorder throws an exception on pressing "Start"

I am opening GUI recorder with recorder.sh
I leave all settings by default. When pressing Start it does not do anything and shows the following log in the terminal

12:25:24.584 [WARN ] i.n.b.ServerBootstrap - Unknown channel option ‘TCP_NODELAY’ for channel ‘[id: 0x657b8f47]’
