Error message

BinanceSpotHttpError::ResponseParseError(message.into())

What it means

response_parse_error wraps a message into BinanceSpotHttpError::ResponseParseError. It signals that a Binance HTTP response arrived but could not be decoded into the expected adapter type (SBE payload, instrument, trade, bar, etc.).

Solutions

1. Upgrade nautilus_trader to a version supporting the current Binance SBE schema
2. Check Binance API status/changelog for breaking changes
3. Verify network path (no proxy/CDN mangling responses)
4. Capture the raw response and open an issue if it looks valid

match result { Err(e) if e.to_string().contains("ResponseParseError") => { warn!("Binance response undecodable; upgrading/awaiting schema fix"); schedule_retry_with_backoff(); } Err(e) => return Err(e), Ok(v) => Ok(v) }

When it happens

Trigger: Any spot HTTP response whose body fails parsing — unknown SBE schema version, unexpected JSON/SBE shape, or endpoint returning an error body where a success payload was expected.

Common situations: Binance API schema updates ahead of adapter support; hitting a wrong endpoint/URL; proxies returning HTML error pages; using an outdated nautilus_trader against current Binance APIs.
