Error with hiding WorldMapFrame WorldQuests

So I'm trying to write code that will completely eliminate or at least hide the WorldQuests from the World Map. Just the world quests though nothing else. I believe there is a filter way of doing it but I haven't looked much into it.

Code:
hooksecurefunc (WorldMapFrame, "OnMapChanged", function()

	local mapID = WorldMapFrame.mapID

	for dataProvider, state in pairs (WorldMapFrame.dataProviders) do

		if mapID == dataProvider:GetMap():GetMapID() then
			local taskInfo = C_TaskQuest.GetQuestsForPlayerByMapID(mapID)
	
			if (taskInfo and #taskInfo > 0) then

				local questPins = {}
				
				for pin in dataProvider:GetMap():EnumerateAllPins() do
					if pin.questID then
						questPins[pin.questID] = pin
					end
				end
			
				for i, info  in ipairs (taskInfo) do
					local questID = info.questId
					if (HaveQuestData (questID)) then
						local isWorldQuest = QuestUtils_IsQuestWorldQuest (questID)
						if isWorldQuest and questPins[questID] and questPins[questID].worldQuest then
							dataProvider:GetMap():RemovePin(questPins[questID])
						end
					end
				end
				
			end
			
			break
		end
		
	end

end)
The code above is what I'm using but I keep getting an error with it. I've tried several methods but maybe someone here can see something I'm not seeing.

Clicking on the magnifying glass in the top right of the map allows you to remove most, though perhaps not all world quests from the map.

Yep I want to remove them all lol. That's what I'm trying to do. There are a few that don't get filtered out.

>.< I guess no one has an idea. It seems to be triggering from the Mixins RefreshAll or RefreshAllData calls. Just can't seem to figure a way not to have it call the SetPosition which triggers the error.

This is how I do it:
Lua Code:
  1. local function OrigProviderOnRemoved(self, mapCanvas)
  2.     -- temporary fix to prevent error when removing the original world quest provider, I've notified
  3.     -- Blizzard developers directly about this issue and it should be resolved soon™
  4.     local Map = self:GetMap()
  5.     Map:UnregisterCallback('SetFocusedQuestID', self.setFocusedQuestIDCallback)
  6.     Map:UnregisterCallback('ClearFocusedQuestID', self.clearFocusedQuestIDCallback)
  7.     Map:UnregisterCallback('SetBountyQuestID', self.setBountyQuestIDCallback)
  8.  
  9.     MapCanvasDataProviderMixin.OnRemoved(self, mapCanvas)
  10. end
  11.  
  12. for provider in next, WorldMapFrame.dataProviders do
  13.     if(provider.GetPinTemplate and provider.GetPinTemplate() == 'WorldMap_WorldQuestPinTemplate') then
  14.         -- BUG: the OnRemoved method is broken, so we replace it before we remove the provider
  15.         provider.OnRemoved = OrigProviderOnRemoved
  16.         WorldMapFrame:RemoveDataProvider(provider)
  17.     end
  18. end

The reason I overwrite OnRemoved is because of a bug with the order of execution within it.
Whenever that is fixed, you can just do this:
Lua Code:
  1. for provider in next, WorldMapFrame.dataProviders do
  2.     if(provider.GetPinTemplate and provider.GetPinTemplate() == 'WorldMap_WorldQuestPinTemplate') then
  3.         WorldMapFrame:RemoveDataProvider(provider)
  4.     end
  5. end

Thanks for the response p3lim. I've been toying with the DataProviders and have noticed that the order of particular calls are out of whack. One of them being the Refresh one for the pins. I was trying to find a way to get the pins to be removed, but because of the order they where being refreshed and called by SetPoint on the primary Mixin.

It never occured to me to look at removing the DataProvider entirely. I was doing on a pin by pin basis. Thanks for the insight, figured someone would see a different approach then what I was doing.
