chartjs-plugin-annotation: import from chart.js cause "cannot use import statement outside a module"

Hello, When I try to import annotation plugin at NodeJS as follows import annotation from 'chartjs-plugin-annotation' it is causing an error like below

So What I have done to fix it is I downgrade to 2.0.0 and change chartjs-plugin-annotation.esm as follows

import { Element, defaults, Animations, Chart } from 'chart.js/auto' and everything work fines. (That fix doesn’t work at ver 2.1.0)

May I know what is wrong in here as I don’t find similar issue mentioned or Is it only happening to me
