The gwt-elemental JSON library has been removed from Vaadin 25 dependencies and only Jackson 3 is used now. Add-ons that were using gwt-elemental for JSON processing needs to be updated to use Jackson 3.
Be sure to check out @Matti’s post on add-on upgrading for more info Vaadin 25 add-on upgrades
Please use the latest version 6.0.0. It should work with Vaadin 25+.
