What causes "invalid negative order-book update ID" in nautechsystems/nautilus_trader?

Inspect the raw depth response to confirm `lastUpdateId` is a non-negative integer.

invalid negative order-book update ID

Error message

invalid negative order-book update ID

What it means

Thrown in `parse_book_snapshot_response` when the depth snapshot's `last_update_id` is negative and cannot be converted to the unsigned `u64` sequence number required by NautilusTrader's `OrderBook`. Binance should never send a negative update ID, so this is a defensive invariant check against malformed API responses.

Solutions

Inspect the raw depth response to confirm `lastUpdateId` is a non-negative integer.
Re-fetch the snapshot; a single malformed response is usually transient.
If using a proxy/mock, fix the fixture to emit valid non-negative update IDs.
Report a bug if a genuine Binance response contains a negative ID.

Example fix

// before: snapshot from an untrusted source used directly
let book = client.request_book_snapshot(instrument_id, Some(5000)).await?;
// after: retry on malformed snapshots
let book = match client.request_book_snapshot(instrument_id, Some(5000)).await {
    Ok(b) => b,
    Err(e) if e.to_string().contains("invalid negative order-book update ID") => {
        client.request_book_snapshot(instrument_id, Some(5000)).await?
    }
    Err(e) => return Err(e),
};

Defensive patterns

Strategy: validation

Validate before calling

fn has_valid_update_id(snapshot: &BinanceDepth) -> bool { snapshot.last_update_id >= 0 }

Type guard

fn valid_snapshot(s: &BinanceDepth) -> bool { s.last_update_id >= 0 && !s.bids.is_empty() && !s.asks.is_empty() }

Try / catch

match client.request_book_snapshot(id, depth).await {
    Ok(book) => book,
    Err(e) if e.to_string().contains("invalid negative order-book update ID") => retry_snapshot(id, depth).await?,
    Err(e) => return Err(e),
}

Prevention

Re-fetch snapshots on parse errors rather than propagating stale data.
Avoid routing exchange traffic through proxies that rewrite payloads.
Validate fixtures/mocks emit non-negative lastUpdateId.

When it happens

Trigger: Calling `request_book_snapshot` when the Binance `/api/v3/depth` response contains a negative `lastUpdateId` — essentially only possible with a corrupted, mocked, or non-conformant response payload.

Common situations: Proxy or MITM tooling returning synthesized/garbage depth JSON; a test fixture or mock server with negative IDs; a breaking change in the upstream API response schema.
