This is only happening when I try import react queryClient from my src/utils folder I made the declaration inside the createRouter route function itself Now my question is that how can I access this queryClient in my utils function? I know we can access if we are in a component using Route.useRouteContext().queryClient

@Winston hey, as I said I stopped seeing that error when I stopped importing queryClient. I made the declaration inside the src/router.tsx file. Now when I need to access queryClient, I used useQueryClient and its working fine. 
export function useUpdateConversation() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (input: Message.CreateInput) => updateConversation(input),
    onSuccess: (_, variables) => {
      queryClient.invalidateQueries({
        queryKey: ["conversation", variables.conversationID],
      });
    },
  });
}
export function useUpdateConversation() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (input: Message.CreateInput) => updateConversation(input),
    onSuccess: (_, variables) => {
      queryClient.invalidateQueries({
        queryKey: ["conversation", variables.conversationID],
      });
    },
  });
}
