处理Twilio StatusCallBack时遭遇15000内部错误，端点未触发

问题详情 #

• 处理Twilio StatusCallBack事件时触发内部错误，Twilio返回500错误，错误码为15000，描述为internal twilio error
• 负责更新外呼电话状态的函数已完全失效，调试时断点从未触发，确认端点完全未被访问
• 该函数在上周五前运行一切正常

相关代码 #

public async Task GetOutgoingCallStatus(CallStatusParams param)
{
    var conferenceSid = _callService.GetConferenceSidByParticipant(param.CallSid);
    if (param.CallStatus == "no-answer" || param.CallStatus == "busy" ||
        param.CallStatus == "canceled" || param.CallStatus == "failed")
    {
        var agentCallSid = _callService.GetAgentSidByConferenceSid(conferenceSid);
        var call = CallResource.Update(
                      twiml: new Twiml($"<Response><Say>{TwilioSettings.OutboundCallDeclineMessage}</Say><Hangup/></Response>"),
                      pathSid: agentCallSid
                 );
    }
    if (param.CallStatus == "in-progress")
    {
        await _callService.RaiseNotification(param.To, "OUTBOUND_CALL_RECEIVED");
    }
    if (param.CallStatus == "completed")
    {
        _callService.HangUpAllAgents(conferenceSid);
    }
}

有对应错误提示截图及函数结构截图，分别显示Twilio返回的内部错误信息和当前函数的结构。
