function obj = HelperPoolWaitbar(N,message)
if nargin < 2
message = 'PoolWaitbar';
obj.N = N;
obj.ClientHandle = waitbar(0, message);
obj.Queue = parallel.pool.DataQueue;
obj.Listener = afterEach(obj.Queue, @(~) localIncrement(obj));

How are you invoking the function? Are you pressing the green Run button? Are you calling it with a line of code?

Like it says, you're not passing in the required inputs. How did you call it in your script or command window. If you did something like
N = 4;
message = 'Hello POTNURU!';
obj = HelperPoolWaitbar(N,message)
then you should not get that particular error. So, what are your N and message? If they're undefined (like you clicked the green run triangle before you assigned anything to N and message) then of course it won't know what to do and throw an error.
