How do I fix this error with FindPartOnRayWithIgnoreList?

Hi, thanks for taking your time to read this. I am having trouble with figuring out how to solve this error. Basically, I setup an IgnoreList at the SetupLists function and basically here:

local Object = workspace:FindPartOnRayWithIgnoreList(CreateRay, self.ignoreList)

is where the error is. It saysUnable to cast value to Object. I have no idea how to figure out how to fix, I tried adding the if BasePart statement but that did nothing, if anyone can help that'd be really great. Thank you.

local Players = game:GetService("Players")

local Scp106 = {}
Scp106.__index = Scp106

function Scp106.new()
    local self = {}
    setmetatable(self, Scp106)

    -- MAKE SURE TO RESET TABLES BELOW IN CORE STARTING SCRIPT.
    self.ignoreList = {}
    self.connections = {}

    -- MOVE TO CORE SCRIPT LATER.
    self:SetupLists()
    wait(2)
    self:FindConnections()
end

function Scp106:SetupLists()
    for _, Object in pairs(workspace:GetDescendants()) do
        if not Object.Name:match("Floor") then
            if Object:IsA("BasePart") then
                print(Object:GetFullName())
                table.insert(self.ignoreList, Object:GetFullName())
            end
        else
            table.insert(self.connections, Object:GetFullName())
            self.connections[Object:GetFullName()] = 0;
        end
    end
end

function Scp106:FindConnections()
    for _, Player in pairs(Players:GetChildren()) do
        local Character = workspace:FindFirstChild(Player.Name)
        if Character then
            local Humanoid = Character:FindFirstChild("Humanoid")
            local RootPart = Character:FindFirstChild("HumanoidRootPart")

            if (Humanoid and RootPart) then
                local CreateRay = Ray.new(Character.PrimaryPart.CFrame.p, Vector3.new(0, -1000, 0))
                local Object = workspace:FindPartOnRayWithIgnoreList(CreateRay, self.ignoreList)
                if Object.Name:match("Floor") then
                    self.connections[Object:GetFullName()] = self.connections[Object:GetFullName()] + 1;
                end
            end
        end
    end

    for i,v in pairs(self.connections) do
        print(v)
    end
end

return Scp106
