Tanstack + Realtime not working

I'm using tanstack query and I'm not getting updates until I refresh the page

Is there anything obvious I'm doing wrong? This pattern was adapted from the example on the tanstack website https://tanstack.com/router/v1/docs/framework/react/examples/start-convex-trellaux

Here's the project table
projects: defineTable({
      id: v.string(),
      ownerUserId: v.id("users"),
      name: v.string(),
    })
      .index("id", ["id"])
      .index("ownerUserId", ["ownerUserId"]),
projects: defineTable({
      id: v.string(),
      ownerUserId: v.id("users"),
      name: v.string(),
    })
      .index("id", ["id"])
      .index("ownerUserId", ["ownerUserId"]),


This is my getProject code on the backend
async function ensureProjectExists(
  ctx: QueryCtx,
  id: string,
): Promise<Doc<"projects">> {
  const project = await ctx.db
    .query("projects")
    .withIndex("id", (q) => q.eq("id", id))
    .unique();

  invariant(project, `missing project: ${id}`);
  return project;
}

export const getProject = query({
  args: {
    projectId: v.string(),
  },
  handler: async (ctx, args) => {
    const userId = await getAuthUserId(ctx);
    if (userId === null) throw new Error("Not authenticated");
    const project = withoutSystemFields(
      await ensureProjectExists(ctx, args.projectId),
    );
    if (project.ownerUserId != userId) throw new Error("Not authorized");
    return project;
  },
});
async function ensureProjectExists(
  ctx: QueryCtx,
  id: string,
): Promise<Doc<"projects">> {
  const project = await ctx.db
    .query("projects")
    .withIndex("id", (q) => q.eq("id", id))
    .unique();

  invariant(project, `missing project: ${id}`);
  return project;
}

export const getProject = query({
  args: {
    projectId: v.string(),
  },
  handler: async (ctx, args) => {
    const userId = await getAuthUserId(ctx);
    if (userId === null) throw new Error("Not authenticated");
    const project = withoutSystemFields(
      await ensureProjectExists(ctx, args.projectId),
    );
    if (project.ownerUserId != userId) throw new Error("Not authorized");
    return project;
  },
});


This is my queries on the frontend

export const projectQueries = {
  list: () => convexQuery(api.projects.getUsersProjects, {}),
  getProject: ({ projectId }: { projectId: string }) =>
    convexQuery(api.projects.getProject, { projectId }),
};

export function useCreateProjectMutation() {
  const mutationFn = useConvexMutation(
    api.projects.createProject,
  ).withOptimisticUpdate((localStore, args) => {
    const { project } = args;

    const { id: projectId } = project;
    const projectQuery = localStore.getQuery(api.projects.getProject, {
      projectId,
    });
    if (projectQuery) {
      localStore.setQuery(
        api.projects.getProject,
        { projectId },
        {
          id: project.id,
          name: project.initialName,
          ownerUserId: projectQuery.ownerUserId,
        },
      );
    }
  });

  return useMutation({ mutationFn });
}
export const projectQueries = {
  list: () => convexQuery(api.projects.getUsersProjects, {}),
  getProject: ({ projectId }: { projectId: string }) =>
    convexQuery(api.projects.getProject, { projectId }),
};

export function useCreateProjectMutation() {
  const mutationFn = useConvexMutation(
    api.projects.createProject,
  ).withOptimisticUpdate((localStore, args) => {
    const { project } = args;

    const { id: projectId } = project;
    const projectQuery = localStore.getQuery(api.projects.getProject, {
      projectId,
    });
    if (projectQuery) {
      localStore.setQuery(
        api.projects.getProject,
        { projectId },
        {
          id: project.id,
          name: project.initialName,
          ownerUserId: projectQuery.ownerUserId,
        },
      );
    }
  });

  return useMutation({ mutationFn });
}


This is how i render it
export function ProjectChat({ projectId, chatId }: ProjectChatProps) {
  const projectQuery = useSuspenseQuery(
    convexQuery(api.projects.getProject, {
      projectId,
    }),
  );

  if (!projectQuery.data) {
    return null;
  }

  return (
    <div className="flex flex-col">
      <div className="p-2">{projectQuery.data.name}</div>
      <div className="flex">
        <div className="w-[500px] flex-shrink-0">{projectQuery.data.name}</div>
        <div className="flex-grow">test</div>
      </div>
    </div>
  );
}
export function ProjectChat({ projectId, chatId }: ProjectChatProps) {
  const projectQuery = useSuspenseQuery(
    convexQuery(api.projects.getProject, {
      projectId,
    }),
  );

  if (!projectQuery.data) {
    return null;
  }

  return (
    <div className="flex flex-col">
      <div className="p-2">{projectQuery.data.name}</div>
      <div className="flex">
        <div className="w-[500px] flex-shrink-0">{projectQuery.data.name}</div>
        <div className="flex-grow">test</div>
      </div>
    </div>
  );
}

Hi @everyone with everything going on today I forgot to post on discord about our EU launch! We have a region in Dublin now! You can start using it immediately, even for folks on the free plan. https://news.convex.dev/we-finally-got-our-eu-visa/ Stay tuned for more regions but also stay tuned for more infra improvements where we improve latency for teams no matter where their servers are located. Just at the tip of the iceberg re all the optimizations we have lined up.
