If ap.position is undefined or null, accessing ap.position.coin will throw a TypeError, causing the entire function to fail and return []. Enforce defensive programming by safely checking if ap.position exists before mapping.

    return (data.assetPositions ?? [])
      .map((ap) => {
        const pos = ap?.position;
        if (!pos) return null;
        return {
          coin: pos.coin,
          szi: parseFloat(pos.szi),
          entryPx: parseFloat(pos.entryPx ?? '0'),
          unrealizedPnl: parseFloat(pos.unrealizedPnl ?? '0'),
        };
      })
      .filter((p): p is HlPosition => p !== null);

} catch {
return [];
}
