I'm not familiar with Next, but it doesn't look like you've configured IdPrefixProvider as you mentioned in your bug. Can you confirm whether you've tried this?

We also have docs for configuring Fluent with Next 13+ and SSR here: https://react.fluentui.dev/?path=/docs/concepts-developer-server-side-rendering-next-js-appdir-setup--docs

• yes i did it , next.js appDir Provider wrap to the layout.tsx and wrap Fluent ui provider with IdPrefixProvider which example are given into the somewhere in the previous issues on github but still not working.
• this issue appears in the next.js 15 with react 19 RC

[Sean Monahan]

I don't see the provider in layout.tsx? Am I missing something?

this issue appears in the next.js 15 with react 19 RC

Does the issue go away with React 18?
