Error message

系统错误

What it means

sendRedPacket calls WeChat Pay via a third-party relay that returns SYSTEM_ERROR with status 500. The service retries with increasing backoff (1s, 2s, ...), and once retry exceeds 5 it gives up and throws HttpException('系统错误', 500). This means the WeChat red-packet endpoint kept failing server-side through all retries.

Solutions

1. Inspect the logged `result` payload (Logger.error includes it) for the upstream error detail
2. Increase retry count or backoff if the outage is expected to be transient
3. Verify WeChat Pay merchant config (mchid, API certs, red-packet product enabled, balance)
4. Add a circuit breaker so repeated SYSTEM_ERROR fails fast instead of retrying 5 times
5. Surface a user-facing message distinct from generic '系统错误' when retries are exhausted

Example fix

// before
if (retry > 5) {
  throw new HttpException('系统错误', HttpStatus.INTERNAL_SERVER_ERROR);
}
// after
if (retry > 5) {
  Logger.error(`sendRedPacket failed after ${retry} retries`, JSON.stringify(result), 'wxPayService');
  throw new HttpException('微信红包发送失败，请稍后重试或联系客服', HttpStatus.BAD_GATEWAY);
}

if (!openId || !transAmount || transAmount <= 0) {
  throw new Error('sendRedPacket requires openId and a positive transAmount');
}

try {
  return await wxPayService.sendRedPacket(openId, amount, outBizNo);
} catch (err) {
  if (err instanceof HttpException && err.getStatus() === 500) {
    // check outBizNo for duplicate before manual retry to avoid double payout
  }
  throw err;
}

When it happens

Trigger: Calling sendRedPacket when the upstream WeChat/relay API responds { error: 'SYSTEM_ERROR', status: 500 } for more than 5 consecutive retries (retry counter > 5).

Common situations: WeChat Pay merchant-side outage; invalid or unbound merchant configuration for red packets; insufficient merchant balance; upstream relay service degraded — all causing persistent 500s instead of transient ones.
