WebRTC. Why does Failed to set local answer sdp: Called in wrong state: STATE_INPROGRESS error appear?

Question

JavaScript

When I try to connect again, I get an error:

Failed to set local answer sdp: Called in wrong state: STATE_INPROGRESS

As far as I understand - due to the fact that the peer is created, if so, how to reuse it?

Answer 1

The problem was that the handlers were not deleted when they were called again, respectively, they were duplicated, as a result, the offer was sent several times.
