go-hyperliquid v0.26.0 crashed at startup with
panic: runtime error: index out of range [479] with length 464
github.com/sonirico/go-hyperliquid.NewInfo (info.go:75)
NewExchange -> NewHyperliquidTrader -> AutoTrader.NewAutoTrader
-> TraderManager.LoadTradersFromStore -> main.main
The library's NewInfo built the spot-asset map by indexing
`spotMeta.Tokens[spotInfo.Tokens[0]]` directly, but Hyperliquid recently
added spot tokens whose Tokens[0] value (a logical token *index*, not an
array position) was larger than the Tokens slice length. With every
restart the backend panicked before the API server bound, so the
frontend's `/api/*` proxy got connection refused on every poll and the
dashboard rendered "全是 error" toasts.
v0.36 fixes the panic by building `tokensByIndex map[int]SpotTokenInfo`
and looking up by logical index instead of position. Adopting v0.36
required two small adaptations to our wrapper:
- trader/hyperliquid/trader.go: NewExchange grew an extra `perpDexs
*MixedArray` argument. Passing `nil` keeps the existing
"auto-fetch on first use" behavior.
- trader/hyperliquid/trader_sync.go: `Info.NameToAsset(coin) int` was
renamed to `Info.CoinToAsset(coin) (int, bool)` with an `ok` flag.
refreshMetaIfNeeded now treats `!ok || assetID == 0` as "needs
refresh" (the same semantic as the old `assetID == 0`).
Verified: backend rebuilds cleanly, container is healthy, all
Hyperliquid traders load, AI cycles execute, and Hyperliquid order
sync receives the full historical trade window.
