[2.25.0] Model gallery is empty + Error 500 since upgrade to 2.25.0

[yscialom]

LocalAI version:

LocalAI Version v2.25.0 (07655c0)
Docker image: localai/localai:latest-aio-gpu-nvidia-cuda-12 1b02a558e76d

Environment, CPU architecture, OS, and Version:

• Linux Ubuntu 24.10
• CPU: Ryzen 9 5900X
• GPU: NVIDIA GeForce RTX 3060
• Docker: Server Version: 26.1.3

Describe the bug

Since I've upgraded to version 2.25, the list of available models is empty on /browse and /models/available raises a HTTP 500 error.

To Reproduce

1. Create file docker-compose.yaml:

services:
  api:
    image: localai/localai:latest-aio-gpu-nvidia-cuda-12
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8080/readyz"]
      interval: 1m
      timeout: 20m
      retries: 5
    ports:
      - 8080:8080
    environment:
      DEBUG: true
    volumes:
      - .localai//models:/build/models:cached
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]

2. Start the container with docker compose up -d
3. Query the list of models with curl -XGET 'http://localhost:8080/models/available' -H 'accept: application/json'
4. With your favourite web browser, open url http://localhost:8080/browse.

Expected behaviour

Both list all models from https://github.com/mudler/LocalAI/tree/master/gallery.

Observed behaviour

1. curl -XGET 'http://localhost:8080/models/available' -H 'accept: application/json' raises an error 500:

{"error":{"code":500,"message":"yaml: map merge requires map or sequence of maps as the value","type":""}}

2. /browser is empty:
