Unable to restore snapshot v1.16.3 on Docker

Current Behavior

I have a single node docker local setup running Qdrant 1.16.3. When uploading snapshots of the same version via http or dashboard, the snapshot cannot be restored.

• Snapshot was captured using qdrant dashboard.
• Snapshot stored on project file /.snapshots

Docker setup with volume binding:

services:
  qdrant:
    image: qdrant/qdrant:v1.16.3
    container_name: qdrant
    ports:
      - "6333:6333"
      - "6334:6334"
    volumes:
      - ./qdrant_data:/qdrant/storage
    restart: always

Potentially corrupted snapshot file:

• extracting the snapshot file and inspecting ...\.snapshots\21.1.2026 v1.16.3\test_extract\0\wal\first-index shows null

Steps to Reproduce

1. Capture snapshot on local dashboard
2. Upload snapshot via http/local dashboard

Expected Behavior

Restored collection from snapshot.

Possible Solution

Assumed it was a binding issue, but i am able to create, query collections no problem so quite confused here.

Context (Environment)

Detailed Description

Possible Implementation

Start by reproducing the Docker v1.16.3 flow through the dashboard or POST /collections/<collection_name>/snapshots/upload, using the described volume binding and snapshot. Inspect the extracted wal/first-index value alongside the WAL initialization error. Done means the captured snapshot restores successfully without the first-index error.
