Azure functions CallActivityAsync不同函数的值相同

变量IsReplaceAvailable的值始终与isComplete的值相同。看起来函数monitorContext.CallActivityAsync（“getispReplaceAvable”，input.Id）甚至没有执行

            while (monitorContext.CurrentUtcDateTime < endTime)
            {
                // Check the weather
                if (!monitorContext.IsReplaying)
                {
                    bool isComplete = await monitorContext.CallActivityAsync<bool>("SendConfirmationAlert", msg);
                    log.LogInformation($"Checking current course conditions for {input.Id} at {monitorContext.CurrentUtcDateTime}.");
                }

                bool isPlaceAvailable = await monitorContext.CallActivityAsync<bool>("GetIsPlaceAvailable", input.Id);

                if (isPlaceAvailable)
                {
                    // It's not raining! Or snowing. Or misting. Tell our user to take advantage of it.
                    if (!monitorContext.IsReplaying)
                    {
                        log.LogInformation($"Detected place available for {input.Id}. Notifying {input.Phone}.");
                    }

                    await monitorContext.CallActivityAsync("SendPlaceAvailableAlert", msg);
                    break;
                }
                else
                {
                    // Wait for the next checkpoint
                    var interval = await monitorContext.CallActivityAsync<int>("GetInterval", null);
                    var nextCheckpoint = monitorContext.CurrentUtcDateTime.AddMinutes(interval);
                    if (!monitorContext.IsReplaying) { log.LogInformation($"Next check for {input.Id} at {nextCheckpoint}."); }

                    await monitorContext.CreateTimer(nextCheckpoint, CancellationToken.None);
                }

            }

            log.LogInformation($"Monitor expiring.");
        }

while（monitorContext.CurrentUtcDateTime

问题似乎是第一个异步调用（位于

if（！context.isReplaying）{}

中）导致了问题。在while循环之外调用函数

SendConfirmationAlert

时，它会按预期工作。

如果在

getispReplaceAble

函数中添加日志，那么这些日志是否正在被记录？在调试过程中，是否命中调试点？我插入了一个日志和断点，但它只是跳过了函数GetIsReplaceAble。
