Path finding errors, not able to create path?

Hello, I am working on path finding for a zombie AI and it seems that when the zombie is spawned in the game and you are behind a cancollided wall he will create a path. He will find you in the players and label you a target, but he can't create a path to you, but no errors pop up. It seems as if it is just a bug that I don't know how to fix. I was wondering if there was a way to fix this, or to check to see if a path was created, and if it wasn't created maybe he can be deleted from the workspace and respawned somewhere else. I am not quite sure how to check if a path was created. Could anyone give me some pointers?

Here is my code:

function findPath(target)
    showImage()
    local path = game:GetService("PathfindingService"):CreatePath()
    path:ComputeAsync(myRoot.Position,target.Position)
    local waypoints = path:GetWaypoints()
    local success = path.Status == Enum.PathStatus.Success
    if success then
        for _, waypoint in ipairs(waypoints) do
            if waypoint.Action == Enum.PathWaypointAction.Jump then
                myHuman.Jump = true
            end
            myHuman:MoveTo(waypoint.Position)
            local timeOut = myHuman.MoveToFinished:Wait(1)
            if not timeOut then
                myHuman.Jump = true
                print("Path too long!")
                findPath(target)
                break
            end
            if checkSight(target) then
                repeat
                    --print("Moving directly to the target")
                    myHuman:MoveTo(target.Position)
                    attack(target)
                    wait(0.1)
                    if target == nil then
                        break
                    elseif target.Parent == nil then
                        break
                    end
                until checkSight(target) == false or myHuman.Health < 1 or target.Parent.Humanoid.Health < 1
                break
            end
            if (myRoot.Position - waypoints[1].Position).magnitude > 20 then
                print("Target has moved, generating new path")
                findPath(target)
                break
            end
        end
    end
end
