I also encountered the same problem

I have the same issue. Updated from m112 ffbb6f4 to m120 8a486a2. The exception is:

libc++abi: terminating due to uncaught exception of type MediaSoupClientError: Failed creating data channel

Triggered from webrtc sdp_offer_answer.cc:2404

observer->OnSetLocalDescriptionComplete(RTCError::OK());

Which doesn't make sense to me because it looks like OK error and should return true from error.ok(). Anyway here's the part of mediasoup that triggers the error:

PeerConnection.cpp

rtc::scoped_refptr<webrtc::DataChannelInterface> PeerConnection::CreateDataChannel(
    const std::string& label, const webrtc::DataChannelInit* config)
  {
  	MSC_TRACE();

  	const auto result =
  	  this->pc->CreateDataChannelOrError(label, config);

  	if (result.ok())
  	{
  		MSC_DEBUG("Success creating data channel");
  	}
  	else
  	{
  		MSC_THROW_ERROR("Failed creating data channel");
  	}

  	return result.value();
  }

Happens every time I try to create a video producer:

try sendTransport.createProducer(
	for: videoTrack,
	encodings: nil,
	codecOptions: options, // ["videoGoogleStartBitrate": 1000]
	codec: nil,
	appData: nil
	)

Will appreciate any help.

Found the issue, it's this call. It shouldn't throw because ok() is true. It's fixed in the upstream.

@fedulvtubudul could you please sync libmediasoupclient? Thanks

Also getting this. Crash on any new consumer.
