Troubleshooting
"Private key is required" error
Make sure you're passing a valid private key to the constructor:
// ✅ Correct
const client = new QueryFlowClient("0xabc...");
// ❌ Wrong
const client = new QueryFlowClient(""); // Empty
const client = new QueryFlowClient(undefined); // Undefined
"Wallet client not initialized" error
You're using tx mode but the wallet setup failed. Check your private key format.
Payment transaction fails
- Ensure you have enough testnet AVAX
- Check that you're on the Fuji network
- Verify the private key has funds
