Typechecking warning

[weakroblox35]

What does this mean and how can I get rid of it? The function just checks a table content then returns a boolean.

Not all code paths return a boolean. Try adding return false to the end of your function.

In addition to what @bluebxrrybot said, you can also modify the return type to boolean?, which makes returning a boolean optional

[weakroblox35]

Adding it does nothing and the warning remains.

function Check(Table:{}):boolean?
	if type(Table) ~= "table" then
		return false
	end
	local Unpacking = table.unpack(Table)
	if typeof(Unpacking[1]) ~= "Instance" then warn("ARGUMENT 1 IS NOT AN INSTANCE.") return false end
	if type(Unpacking[2]) ~= "string" then warn("ARGUMENT 2 IS NOT AN STRING.") return false end
	if type(Unpacking[3]) ~= "string" or type(Unpacking[3]) ~= "boolean" then warn("ARGUMENT 3 IS NOT ACCEPTABLE..") return false end
end

Then, you should add return false at the end of your function as the first reply mentions

weird, because that should work right? No return is nil lol

Maybe try boolean | nil

[weakroblox35]

Same error. Putting return true removed the warning.
