wyoming_piper handler crashes when trying to synthesize any text - File not found

[mxmo0rhuhn]

Hi all
Thanks a lot for the awesome TTS project! I really enjoy tinkering with it.
However, after several working texts yesterday. Piper suddenly stopped working within my Home Assistant installation. I restarted the add-on as well as Home Assistant but nothing seems to work

Versions:
Core: 2023.12.3
Supervisor: 2023.11.6
Operating System: 11.2
Frontend: 20231208.2
Piper Add-on version: 1.4.0

Service call:

service: tts.speak
data:
  media_player_entity_id: media_player.sonos_roam
  message: "Today is {{ now().strftime( '%B %d, %Y') }}"
target:
  entity_id: tts.piper

Output of the add-on:

Same problem here.
Tried the master and the v1.4.0 branch.

Found the issue. If you print out stderr from the piper call you will find
piper: error: unrecognized arguments: --json-input

I am using the python version of piper by the way: piper-tts

EDIT:
Using the cpp version for now, works fine here.

I am getting this error when using a custom built piper. Not sure how to get the piper binary logs to print to stdout.

Try what I described here #7 to see if solves your problem.

Not sure what you mean by cpp and python version, but I have the --json-input and everything is working (Piper Add-on).

Piper is crashing when writing the resulting audio wav file, so the instruction to open it to continue is failing.
You mention it was working. Anything changed? Missing space in disk, permissions, etc?

Unfortunately I did not change anything. I restarted the add-on & the HA server a few times but this did neither result in a consistent result nor a better situation
