Type '(any) -> ()' could not be converted into '(any) -> g52'

BindableEvent invoke gives strange error.

OnButtonPressed.OnInvoke = function(Response)
	
end

In the script editor this is underlined for some reason.

When I hover on it, it says " Type ‘(any) → ()’ could not be converted into ‘(any) → g52’ ". Can anyone tell me how to fix this?

I am using --!strict by the way, please don’t ask me to remove it, I want to solve this error without removing strict.

Do you have any code within that function yet? If so, what is it and what are you returning? Also, I assume you mean a RemoteFunction and not a RemoteEvent?

@sleitnick @takticiadam
It’s a BindableFunction.

Here is the code, its being used in SendNotification by the way.

local OnButtonPressed: BindableFunction = Instance.new("BindableFunction")

OnButtonPressed.OnInvoke = function(Response: string)
	if (Response == "Yes") then
		MarketplaceService:PromptProductPurchase(LocalPlayer,1121741086)
		return true
	end
	return false
end

OnButtonPressed.Parent = script

StarterGui:SetCore("SendNotification",{
		Title = "place holder",
		Text = "place holder",
		Icon = "place holder",
		Button1 = "Yes",
		Button2 = "No",
		Callback = OnButtonPressed
	})

I think this is just a bug with the type-checker, or at least with the configuration of BindableFunctions. Your code is valid. It only one return type (boolean), and the type-checker seems to pick up on that fine.

I wonder what “g33” is supposed to be?

Whats the error? you just added the “: string” thing but you didnt explain whats wrong

I have mentioned it in the screenshot.

My bad, sorry it was really small that not enough to me notice it.

#9

Have you tried specifying the return of the function? Whatever g33 is could be a default that’s throwing it off.
