the scene is that there is a short-live activity , it may failed due to outer service quality, the outer service might down for hours, in the time the activity won’t be success,. but there a way to finish the job manually which workaround the outer service. so is there a way to skip an err activity? besides the way has to comply with - non-blocking - no code change of the running workflow/activity, no worker restart * * * what i have tried . 1. _tctl activity complete to skip_. it doesn’t work for the scene cause the activity failed immediately, u can’t complete a failed activity 2. _interceptor and signal_ . i thought the best place is “activityInboundInterceptor ExecuteActivity”, but can’t find a non-blocking way to pass a signal to it ---

1. Here is the [issue](https://github.com/temporalio/temporal/issues/987) to get this fixed. 2. Activity interceptor wraps the activity execution, not its invocation by the workflow. Use [WorkflowOutboundInterceptor](https://github.com/temporalio/sdk-go/blob/7151653bdadc6d2645d3543bfc3ad5dfd3bd4551/internal/interceptor.go#L175) which runs in the workflow context instead. ---

tks for answering 1. seems the issue won’t be close recently . 2. workflowOutboundInterceptor can’t handle the scene i thought, “workflowOutboundInterceptor ExecuteActivity” return a Future, couldn’t handler activity here, any suggestions? 3. is there any other ways to skip a short-live activity when it’s failed ? has to change the workflow code and restart woker? ---

1. I don’t understand your comment. The outbound interceptor intercepts an activity invocation from the workflow. See this [example](https://github.com/temporalio/sdk-go/blob/7151653bdadc6d2645d3543bfc3ad5dfd3bd4551/interceptor/tracing_interceptor.go#L353). You can listen to signal in the interceptor, then cancel activity on signal. ---

tks for your patience maybe there is some misunderstanding , let me show u the code with the codes below. when i send signal “SkipErrActivityForOneTime=true” , the whole workflow was canceled, but my expect is cancel/skip the activity only. what is wrong? * * * the workflow ```auto func GreetingWorkflow(ctx workflow.Context, name string) (string, error) { options := workflow.ActivityOptions{ ... } ctx = workflow.WithActivityOptions(ctx, options) var result string // failed immediately err := workflow.ExecuteActivity(ctx, activities.ComposeGreeting, activities.GreetingParam{"jack"}).Get(ctx, &result) if err != nil { return "", err } // other activities ... return "", nil } ``` * * * the activity ```auto // failed immediately func ComposeGreeting(param GreetingParam) (string, error) { return "", errors.New("bad error greeting") } ``` * * * the interceptor save param pointer to ctx ```auto func (w *workflowInboundInterceptor) ExecuteWorkflow( ctx workflow.Context, in *interceptor.ExecuteWorkflowInput, ) (interface{}, error) { // save the pointer to ctx cancelFuncP := cancelFuncStruct{cancelFunc: nil, cancelActivity: nil} ctx = workflow.WithValue(ctx, "pauseCancelFunc", &cancelFuncP) flowControl := workflows.FlowControl{} ctx = workflow.WithValue(ctx, "flowControl", &flowControl) // fetch signal aync workflow.Go(ctx, flowSignalHandler) return w.Next.ExecuteWorkflow(ctx, in) } ``` expose the cancelHandler to ctx ```auto func (w *workflowOutboundInterceptor) ExecuteActivity(ctx workflow.Context, activityType string, args ...interface{}) workflow.Future { childCtx, cancelHandler := workflow.WithCancel(ctx) cancelFuncP := ctx.Value("pauseCancelFunc").(*cancelFuncStruct) cancelFuncP.cancelActivity = cancelHandler wFuture := w.Next.ExecuteActivity(childCtx, activityType, args...) return wFuture } ``` flowSignalHandler to handle singal ```auto func flowSignalHandler(ctx workflow.Context) { flowControl := ctx.Value("flowControl").(*workflows.FlowControl) signalChan := workflow.GetSignalChannel(ctx, "flowControl") // keep handler signal in the loop for { signalChan.Receive(ctx, &flowControl) if flowControl.SkipErrActivityForOneTime == true { // try to cancel activity execution cancelFuncP := ctx.Value("pauseCancelFunc").(*cancelFuncStruct) cancelFuncP.cancelActivity() } } } ``` ![image](https://us1.discourse-cdn.com/flex016/uploads/temporal/original/2X/f/f4047fab28aeaec18cf2dc29139ee32f1d088ce3.png) ---

I guess that you canceled the activity, which caused it to return a cancellation error. The workflow handled that error by returning it from the workflow function. This was interpreted as workflow cancellation. I think you want to retry the activity in the case of a cancellation request.
