zustand empty on inital render

Hello,

I am currently using nextjs, trpc and zustand. I'm running into a problem where my zustand state is undefined on reacts inital render of the page.

- I use trpc's prefetch function is a layout.tsx file to fetch data on the server, the data here is used on all routes within my

/dashboard

/dashboard

directory (this data is mainly for my dashboard sidebar
- the data is being hydrated with trpcs hydrateclient comonent
- i have a loading.tsx file to catch all trpc queries which are still running, if there are any a loading state will be displayed until all data is fetched.

export default async function Layout({ children, params }: Readonly<Props>) {
  const { workspaceId } = await params;

  await api.workspace.list.prefetch();
  await api.connections.list.prefetch({ workspaceId });

  return (
    <HydrateClient>
        <SidebarProvider>
          <AppSidebar workspaceId={workspaceId} />
          <main className="p-4 w-full">{children}</main>
        </SidebarProvider>
      <Toaster />
    </HydrateClient>
  );
}

export default async function Layout({ children, params }: Readonly<Props>) {
  const { workspaceId } = await params;

  await api.workspace.list.prefetch();
  await api.connections.list.prefetch({ workspaceId });

  return (
    <HydrateClient>
        <SidebarProvider>
          <AppSidebar workspaceId={workspaceId} />
          <main className="p-4 w-full">{children}</main>
        </SidebarProvider>
      <Toaster />
    </HydrateClient>
  );
}

Here is my workspace selector component, it is at the top of my dashboard sidebar and shares state between different pages on the dashboard, which is why i plan on using zustand. I am only using zustand for the current selected workspace at this time, as I know trpc has a built in state management cache for data retrieved from the server.

// workspaceId is passed in from my page layout.tsx file (it is obtained through the URL search params, eg: /dashboard/workspaceId/home
export const WorkspaceSelector = ({ workspaceId }: Props) => {
  const { data: workspaces } = api.workspace.list.useQuery();
  const {selectedWorkspace, setSelectedWorkspace} = selectedWorkspaceStore();

  useEffect(() => {
    const workspace = workspaces?.find((workspace) => workspace.id === workspaceId);
    if (!workspace) return;
    setSelectedWorkspace(workspace); // store the current selected workspace in zustand
  }, [workspaceId, workspaces]);

// workspaceId is passed in from my page layout.tsx file (it is obtained through the URL search params, eg: /dashboard/workspaceId/home
export const WorkspaceSelector = ({ workspaceId }: Props) => {
  const { data: workspaces } = api.workspace.list.useQuery();
  const {selectedWorkspace, setSelectedWorkspace} = selectedWorkspaceStore();

  useEffect(() => {
    const workspace = workspaces?.find((workspace) => workspace.id === workspaceId);
    if (!workspace) return;
    setSelectedWorkspace(workspace); // store the current selected workspace in zustand
  }, [workspaceId, workspaces]);
