Nativescript 4.2 timeline-view

Question

Я запускаю timeline-view в версии 4.2 nativescrip, чтобы увидеть дерево, но у меня ошибка при просмотре графики в браузере, просто ничего не появляется и в javascript у меня есть следующее:

Uncaught DOMException: Failed to execute 'createPattern' on 'CanvasRenderingContext2D': The image argument is a canvas element with a width or height of 0.
