I am using Simple Peer to connect 2 clients over webRTC

While trying to send the offer to the receiver I am getting

If there is any tool to format it, please let me know, I will do it. also, I read, that this could be a codec problem, so I tried to replaced profile-level-id=42001f with profile-level-id=42e01f this did not do the trick.

Why does webRTC have to be so difficult? it might as well be called hellRTC also, why is the extension part of the SDP is full of URLS?.. it just doesn't look something you want to pass in your request or signaling.

Thank you.
