Error Detail Type: Failed to set remote offer sdp: Failed to set remote video description send parameters for m-section with mid='1

the sdp is this:

Let me try. I'm using a Signaler Server to pass the Offer from peer to peer, instead of "GetOtherPc" function in the examples. So I'm reconstructing the RTCSessionDescription object in the remote side(callee). The sdp string is identical to the one that was generated to the local peer (caller) and the type is properly set in the initial data. But trying to set this new created object with the SetRemoteDescription produces this error. This only happens when RECONSTRUCTING RTCSessionDescription from type and sdp string. It doesn't happen in the examples where the RTCSessionDescription object is passed by ref.
