Hey all, My team is currently using NextJS and "@thoughtspot/visual-embed-sdk": "1.36.1",. Today, I tried to update to version 1.43 but show this error shows up during my build.

I'm assuming this is due to an unsafe call on window in a server component. possibly in init?

Hi @tkimia This error happens because newer versions of the ThoughtSpot embed SDK rely heavily on window and can’t be imported or executed in Server Components. With Next.js + Turbopack, this triggers window is not defined during prerendering. To fix it, move all SDK usage (including init()) into a Client Component or load it via a dynamic import with ssr: false.

client components still pre-render on the server (for future reference)
