Root Cause

The caller's context was canceled (e.g., HTTP request aborted, parent context deadline hit, or explicit cancel()) before the RPC completed.

generic

中文

在 RPC 完成前调用方的 context 被取消（例如 HTTP 请求中止、父 context 超时或显式 cancel()）。

Workarounds

  1. 90% success 
    Detach from the request context for background work:
ctx = context.WithoutCancel(ctx)
// or use context.Background() with an explicit timeout
  2. 85% success 
    Distinguish cancellation from real failures:
if status.Code(err) == codes.Canceled {
    return // caller went away, do not log as error
}

Dead Ends

Common approaches that don't work:

  1. 99% fail

    An already-canceled context immediately fails every subsequent call.

  2. 80% fail

    The cancellation originates on the client side; server timeouts are irrelevant.
