langium can not upgrade to 3.0.0

[zrwsmd]

when i upgrade to 3.0.0,i replace my dependecies from "langium": "^1.1.0", to "langium": "~3.0.0",but an error

i notice in node_modules ,it has changed to 3.0.0,but my project can not apply it

i assume you need to change your project setup from cjs to esm as langium is esm since version 2.0
maybe you skaffold a new project with the current cli and compare

[zrwsmd]

my project is esm

[cdietrich]

i propose you try the scaffold thing anyway and compare

@zrwsmd any update on this here? It may also help if you provide a repo that highlights the issue at hand (assuming you can share what you're working on).
