Throw `json` in middleware not working for route rendered on server

I have a basic role check in server middleware. In the loaderData function of a Route, it makes a call to a server function using that middleware. However, the server crashes when the route attempts to be loaded by a server without the required role. Any reason why this would be? My middleware: 
export const requireRoleMiddleware = (requiredRole: User['role']) =>
  createMiddleware({ type: 'function' })
    .middleware([userRequiredMiddleware])
    .server(async ({ next, context }) => {
      const userRole = context.userSession!.user.role;

      if (roleHierarchy.indexOf(requiredRole) < roleHierarchy.indexOf(userRole)) {
        throw json({ error: 'Forbidden' }, { status: 403 });
      }
      return next({ context: { userSession: context.userSession } });
    });
export const requireRoleMiddleware = (requiredRole: User['role']) =>
  createMiddleware({ type: 'function' })
    .middleware([userRequiredMiddleware])
    .server(async ({ next, context }) => {
      const userRole = context.userSession!.user.role;

      if (roleHierarchy.indexOf(requiredRole) < roleHierarchy.indexOf(userRole)) {
        throw json({ error: 'Forbidden' }, { status: 403 });
      }
      return next({ context: { userSession: context.userSession } });
    });

"crashes" how? probably best if you can provide a complete minimal example repository
