Vaadin 24 NotSupportedError vaadin-checkbox

Flow
1

I have upgraded my SpringBoot webapp from Vaadin 23 to Vaadin 24. When running the application locally I received an error inside the browser.

Uncaught (in promise) DOMException: Failed to execute 'define' on 'CustomElementRegistry': the name "vaadin-checkbox" has already been used with this registry
    at window.customElements.define (http://localhost:9092/?continue:6:829)
    at http://localhost:9092/VAADIN/build/generated-flow-imports-fdb85f42.js:3297:125

Error points to

class ro extends S2(k(x(z))) {
    static get is() {
        return "vaadin-checkbox"
    }
    static get template() {
        return y`
      <div class="vaadin-checkbox-container">
        <div part="checkbox" aria-hidden="true"></div>
        <slot name="input"></slot>
        <slot name="label"></slot>
      </div>
      <slot name="tooltip"></slot>
    `
    }
    ready() {
        super.ready(),
        this._tooltipController = new K(this),
        this.addController(this._tooltipController)
    }
}
customElements.define(ro.is, ro);

Upon running vaadin:clean-frontend, vaadin:prepared-frontend and vaadin:build-frontend the error stops occuring, however running mvn verify will trigger the error again.

I have tried running mvn dependency:tree and mvn dependency:analyze-duplicate without success.

I attached my pom.xml in case it might help.

Make sure to use the latest versions of your add-ons and that they are compatible with V24.

will double check tomorrow, certainly something isn’t compatible, I just couldn’t pinpoint it yet.

ok it’s solved, was indeed an outdated addon
