TextChannel:DisplaySystemMessage() erroring out for some reason

Hello,

I am trying out the new TextChatService, so far I’ve created my own UI, and now I need to add the functionality. Unfortunately, TextChatService is really undocumented and I’ve come to an error that I do not know how to fix.

When I execute the following code:

TextChannel:DisplaySystemMessage("This is a message.", "SystemMessage")

These errors come up:

cannot resume non-suspended coroutine

Error occurred while calling TextChannel.OnIncomingMessage: cannot resume non-suspended coroutine

Here is the whole function that is attached to TextChannel.OnIncomingMessage:

local function RecieveMessage(message : TextChatMessage) 										
	if message.Metadata == "" then
		if message.Status == Enum.TextChatMessageStatus.Success then
			local NewChatMessage = MessageTemplate:Clone()

			if message.TextSource then
				local colorHex = getColorFromName(message.TextSource.UserId):ToHex()
				NewChatMessage.Text = "<font color='#" .. colorHex .. "'>[" .. message.PrefixText .. "]</font>: "..message.Text
				NewChatMessage.Parent = MessageTemplate.Parent
				NewChatMessage.Visible = true
			end
			
		-- THE CODE BELOW IS WHAT ERRORS OUT
		elseif message.Status == Enum.TextChatMessageStatus.Floodchecked then
			message.TextChannel:DisplaySystemMessage("too many messages", "SystemMessage")
			
		-- THE CODE BELOW IS WHAT ERRORS OUT
		elseif message.Status == Enum.TextChatMessageStatus.MessageTooLong then
			message.TextChannel:DisplaySystemMessage("long message", "SystemMessage")
	
		end
		
	elseif message.Metadata == "SystemMessage" then
		local NewChatMessage = MessageTemplate:Clone()

		NewChatMessage.Text = "<font color='rgb(255, 50, 50)'><i>"..message.Text.."</i></font>"
		NewChatMessage.Parent = MessageTemplate.Parent
		NewChatMessage.Visible = true

	end
	
end

So, does anybody have any clue as to what I am doing wrong here?
