Synchronization Issues with ARM64 Docker Deployment - Reading Progress and Statistics Not Syncing Correctly

[dengxuezhao]

Description:

I seem to have encountered a bug with my ARM64-based Docker deployment. While the service reports successful synchronization for both reading progress and statistics, the data doesn't actually propagate across devices.

Symptoms:

1. Reading Progress Sync:
   Upload shows "success" status
   Other devices fail to retrieve progress with error: "Document information not found"
   Sync logs show successful GET/PUT operations but no data transfer
2. Reading Statistics Sync:
   System reports "sync successful"
   No corresponding data appears in today's timeline
   Logs show repeated 404 errors for statistics.sqlite3 before PUT operations

Log Excerpts:

Environment:

Architecture: ARM64
Deployment: Docker Compose
Image: submartingaie/kompanion:latest
docker-compose.yml:

version: '3'
services:
  postgres:
    image: postgres:16
    container_name: ko-postgres
    restart: unless-stopped
    volumes:
      - ./pgdata:/var/lib/postgresql/data
    environment:
      POSTGRES_USER: 'user'
      POSTGRES_PASSWORD: 'asf'
      POSTGRES_DB: 'postgres'
  app:
    image: submartingaie/kompanion:latest
    container_name: ko-web
    restart: unless-stopped
    user: 1001:1001
    ports:
      - 8322:8080
    volumes:
     - ./data:/data
    environment:
      KOMPANION_PG_URL: 'postgres://user:asf@postgres:5432/postgres'
      KOMPANION_AUTH_USERNAME: 'user'
      KOMPANION_AUTH_PASSWORD: 'asfasf'
      KOMPANION_BSTORAGE_PATH: '/data/books'
    depends_on:
      - postgres

Reproduction Steps:

Deploy using the provided compose file on ARM64
Sync reading progress between devices
Observe successful upload but failed retrieval
Check statistics timeline for missing data

Expected Behavior:

Progress should be retrievable across devices
Statistics should appear in timeline after sync
