How the "TaskCApi.Broadcast" works？

[wxk0248]

I created a script task in /gamed/config/tasklist/tasklist1.lua, hoping to trigger a broadcast after some logic, but I don't know how it works.
e.g.

--完成该任务时服务器调用   	OnAward = function(TASKINTERFACE_POINTER, bSuccess)   		if bSuccess then			math.randomseed(os.time())			local luckValueID = 10	--幸运值的声望id			local luckGrade = TaskCApi.GetTaskCompleteTimesFromFinishTimeTaskList(TASKINTERFACE_POINTER,15372)	--幸运等级			local rand = {333,250,200,166,125,111}			if luckGrade < 6 then				local temp = math.random(1,1000)				if temp <= rand[luckGrade+1] then					TaskCApi.ModifyTaskFinishCnt(TASKINTERFACE_POINTER, 15372, 1)		--幸运等级+1					TaskCApi.DeliverNewTask(TASKINTERFACE_POINTER,15420)				--仅用于喊话的任务				else					TaskCApi.Broadcast(TASKINTERFACE_POINTER ,15371, TaskBroadcastChannel.Trade)				end			end			TaskCApi.DeliverRegionReputation(TASKINTERFACE_POINTER,luckValueID,-66)	--收幸运值   		end   		return 0   	end

In "TaskCApi.Broadcast(TASKINTERFACE_POINTER ,15371, TaskBroadcastChannel.Trade)"，where to set the broadcast text?

see 2 files:
task_list_text.lua and task_list_text_string.lua

example:
TaskCApi.Broadcast(TASKINTERFACE_POINTER ,14754,TaskBroadcastChannel.Trade)

task_list_text.lua:
TaskListText[14754]={
TaskTributeText = TaskListTextString[14754].TaskTributeText
}

task_list_text_string.lua:
TaskListTextString[14754]={
TaskTributeText = "^ffd700You received 1 point of Dedication.",
}

I tried it. It seems that there is something wrong with it. It can produce a broadcast, but it shows"error" rather than the contents of broadcast.
