Why can't I print the Internal Values provided by Changed event?

Hello, I was using the Changed event on the Humanoid of my player to print out what is changing as I move

humanoid.Changed:connect(function(property)
    print(property)
end)

and my output returns: "MoveDirection" "MoveDirectionInternal"

However, when I use the following code to print out the values of all properties changed:

humanoid.Changed:connect(function(property)
    print(humanoid[property])
end)

My output returns: "0, 0, -1" "MoveDirectionInternal is not a valid member of Humanoid"

I was wondering why this happens and if there are ways to print Internal values or skip over them?

The 'property' parameter is the property that was changed, not the value is was changed to.

Take this code for example:

Code:

local Part = Instance.new("Part")
Part.Parent = workspace

Part.Changed:Connect(function(Property)
	print("Name of property: "..Property)
	print("New value of property: "..Part[Property])
end

wait()

Part.Name = "I changed this property"

Output:

--> Name of property: Name
--> New value of property: I changed this property

Source: Instance.Changed

Hope this helps.
