Testing Piper: 'No such file or directory:'

Sending this test message from dev tools > Actions fails with the No such file or directory message in Piper's stderr output. So, HA and Piper are sort of talking to each other.

    Hello, this is a test of the emergency broadcast system.

I installed Wyoming-Whisper and Piper in Docker containers using these images and with HA 2025.9.1 also in docker on another box:

rhasspy/wyoming-whisper:latest
lscr.io/linuxserver/piper:latest

(I used the lscr.io image since it seems Piper has moved off of rfasspy and lscr.io seemed current.
Per the rfasspy github site:Development has moved: https://github.com/OHF-Voice/piper1-gpl)

I then added the two integrations pointing at their shared host IP and their individual Ports. Both programs have populated their data directories referenced in the docker-compose file,

The mopidy. media player works fine with the picotts TTS engine. I'm hoping for something with better fidelity than picotts,

Thoughts?
