• The withdrawal is not yet claimable (still processing)
• The withdraw key is invalid

try {
  const claim = await sdk.vaultClaim(withdrawKey);
  console.log("Claimed successfully");
} catch (error) {
  if (error.message.includes("already been claimed")) {
    console.log("This withdrawal was already claimed");
  } else if (error.message.includes("not yet claimable")) {
    console.log("Please wait for processing to complete");
  }
}

Notes

• Wallet must be connected via connectAccount() before calling
• The claimed USDC is sent directly to your connected wallet address
