It is most likely happening because you are trying to get info before the router finished its configuration. I will probably try to raise a proper error for this.

Yes, but this happens when reboting replicas (cartridge stop && catridge start) with Cartridge WebUI loaded, so cartridge WebUI polls backend and periodically described shit happens.
