What is the standard approach to initialize the Genesys Cloud Messenger SDK in a Next.js 14 application without triggering CORS failures during server-side rendering? The standard genesyscloud-messaging-sdk script injection fails because the browser blocks requests to the Genesys endpoints when the page hydrates on the server.
I see Access-Control-Allow-Origin missing in the response headers for the initial handshake. The code snippet const sdk = new GenesysCloudMessagingSdk(...) throws a network error immediately. How do I bypass this for the widget load?
Have you tried disabling server-side rendering for the messenger component to prevent the initial handshake from hitting the backend? Next.js 14 defaults to SSR, which triggers the CORS error because the browser expects client-side origin headers that the server request doesn’t provide.
Wrap your SDK initialization in a dynamic import with ssr: false to ensure it only runs in the browser context. This forces the hydration to happen client-side, allowing the fetch requests to Genesys endpoints to include the correct Origin header and bypass the preflight failure.
const Messenger = dynamic(() => import(‘../components/Messenger’), { ssr: false });
Check your import strategy. The docs state “The SDK must be initialized in a browser environment.” Server-side rendering breaks this rule. Use dynamic imports to force client-side execution.
