I am getting error when add Calendar in my layout. (TypeError) : $0.addEven

I am getting error when add Calendar in my layout.
(TypeError) : $0.addEvents is not a function

Can you please give me some additional details about the environment? (Vaadin version, used browser, etc.). Also have you checked, if the npm modules folder contains the addon files and if they are recognized in the dev tools of the browser?

<vaadin.version>14.0.5</vaadin.version>

<fullcalendar.version>2.0.0.RC2</fullcalendar.version>
<fullcalendar.scheduler.version>2.0.0.RC1</fullcalendar.scheduler.version

Node Version : v10.16.3

Browser : Chrome

Os : Windows

node_module also contains the addon files.

I can reproduce the problem, but cannot tell yet where it comes from. Please try to add as vaadin plugin goal “build-frontend”, for instance:

com.vaadin vaadin-maven-plugin ${vaadin.version} prepare-frontend build-frontend

This should fix the problem for now (moves the npm dependency resolvation from runtime to build time)
