Error Handling

Common Errors

  • "Authentication required": User not logged in
  • "KYC verification required": KYC not completed
  • "Invalid trade deal participants": Participant validation failed
  • "Collateral already deposited": Attempting to deposit collateral twice
  • "Unauthorized to settle": User lacks settlement permissions
  • "Trade deal not in settleable state": Invalid status for settlement

Error Recovery

async function handleTradeDealError(dealId: string, error: any, operation: string): Promise<void> {
  try {
    const tradeDeal = await new Parse.Query('TradeDeal')
      .equalTo('objectId', dealId)
      .first({ useMasterKey: true });

    if (tradeDeal) {
      // Log error event
      await logTradeDealEvent(dealId, 'error', `${operation} failed: ${error.message}`, 'system');

      // Send error notification to participants
      await sendErrorNotification(tradeDeal, error, operation);

      // Attempt automatic recovery for certain errors
      if (isRecoverableError(error)) {
        await attemptErrorRecovery(dealId, operation, error);
      }
    }
  } catch (recoveryError) {
    console.error('Error recovery failed:', recoveryError);
  }
}
