Having always loading model '' with backend piper error

[emircanerkul]

Also tried other models but still same. What could be the reason? using linux executable on ubuntu 24.10 with 6800xt

curl http://192.168.1.40:8080/tts -H "Content-Type: application/json" -d '{
   "backend": "piper",
   "input":"HELLO!",
   "model": "en-us-ryan-high.onnx"
 }' | aplay
