to simplify, when RTCPeerConnection.createLocalDescription succedeed create the following SDP:

v=0\r\no=mozilla...THIS_IS_SDPARTA-64.0 9099648978096812984 2 IN IP4 0.0.0.0\r\ns=-\r\nt=0 0\r\na=fingerprint:sha-256 33:5E:BD:FD:A3:94:47:9A:A5:97:4E:2F:CA:E9:98:F6:34:8A:F2:9B:70:F3:12:86:D4:2B:5E:47:C0:23:DC:43\r\na=ice-options:trickle\r\na=msid-semantic:WMS *\r\nm=audio 55331 RTP/SAVPF 0 101 109 8 9\r\nc=IN IP4 192.168.33.222\r\na=candidate:0 1 UDP 2122252543 192.168.33.222 55331 typ host\r\na=candidate:1 1 TCP 2105524479 192.168.33.222 9 typ host tcptype active\r\na=candidate:0 2 UDP 2122252542 192.168.33.222 55332 typ host\r\na=candidate:1 2 TCP 2105524478 192.168.33.222 9 typ host tcptype active\r\na=sendrecv\r\na=extmap:1 urn:ietf:params:rtp-hdrext:ssrc-audio-level\r\na=extmap:2/recvonly urn:ietf:params:rtp-hdrext:csrc-audio-level\r\na=extmap:3 urn:ietf:params:rtp-hdrext:sdes:mid\r\na=fmtp:101 0-15\r\na=fmtp:109 maxplaybackrate=48000;stereo=1;useinbandfec=1\r\na=ice-pwd:c3033baabd7147d12439224007a17e7d\r\na=ice-ufrag:61901d25\r\na=msid:{dfb1bf38-d630-4177-82d4-49429fcf7e76} {f5ffca1a-e296-4b66-971c-a3cd25301b46}\r\na=rtcp:55332 IN IP4 192.168.33.222\r\na=rtcp-mux\r\na=rtpmap:0 PCMU/8000\r\na=rtpmap:101 telephone-event/8000/1\r\na=rtpmap:109 opus/48000/2\r\na=rtpmap:8 PCMA/8000\r\na=rtpmap:9 G722/8000/1\r\na=setup:actpass\r\na=ssrc:515396122 cname:{3a4ced06-2d31-4eee-979e-81d67621bee5}\r\n

when RTCPeerConnection.setLocalDescription apply the previous SDP fails with the following error:
Local descriptions must have a=mid attributes.
