gulp4 выдает такую ошибку при изменеие кода

Я собрал прокт спомащю gulp, с ночало код нормально паботал, а на следущи день когда попробавал делать изменение в коде, любые изменение в html, css, js прводят к такой ошибке

[12:14:19] The following tasks did not complete: dev, watch [12:14:19] Did you forget to signal async completion?

и сервер отключаетья приходится каждыи рас включить заново, и http://localhost:3000/ не открывается ажтоматичски, приходится руками набрать, подскажите пожалуиста как это исправеть?.
