WebRTC ICE Candidate could not be added error

Question

I am getting this error when I addICECandidate

var candidate = new RTCIceCandidate({sdpMLineIndex:message.label,
                            candidate:message.candidate});
                        pc.addIceCandidate(candidate);

My candidate is forming correctly still I am getting this error.

Error is: Failed to execute 'addIceCandidate' on 'RTCPeerConnection': The ICE candidate could not be added.

My issue is while creating offer pc.createOffer(setLocalAndSendMessage, onSignalingError, sdpConstraints); here nothing happens neither setLocalAndSendMessage is called neither onSignalingError thats why later on candidate could not be added.
