Solution to this error:

There are two different types of signal to be sent via websockets:

  1. signal from the initiator peer to all other peers (type:offer)
  2. signal from the peer back to the intiator (type:answer) error pops up if you accidently send the first signal back to the initiator instead of the second signal type
