guys anyone can help? I'm building a frontend trading app on Hyperliquid. I can successfully construct and send orders to the /exchange endpoint, but I'm getting a 422 Unprocessable Entity error: 'Failed to deserialize the JSON body into the target type.' My order payload looks correct: { "action": { "type": "order", "orders": [{ "a": 0, "b": true, "p": "100000", "s": "0.0002", "r": false, "t": {"limit": {"tif": "FrontendMarket"}} }], "grouping": "na" }, "nonce": 1780789..., "signature": "0x...", "vaultAddress": null } The issue is the signature. I'm currently using: const signature = await signer.signMessage(JSON.stringify({action, nonce, vaultAddress: null})); But this keeps getting rejected. What is the correct signing method for frontend order placement? Do I need EIP-712? If so, what's the exact domain/types structure? Or should I use the SDK's order() method directly? The docs say 'see Python SDK' but I'm on frontend. Can you show a working example?"
