Unable to playback stream whepsrc Could not reuse transceiver

Reposting my comment as a Issue since I didn't get a response on there.

I have tried the WHIP and WHEP pipeline from issue #414 (closed) with CloudFlare SFU.

WHIP working fine and the video getting streamed.

gst-launch-1.0 videotestsrc pattern=ball ! "video/x-raw,size=1920x1080,rate=30" \ ! videoconvert ! queue ! vp8enc ! rtpvp8pay pt=101 \ ! queue ! "application/x-rtp,media=video,encoding-name=VP8,payload=101,clock-rate=90000" \ ! whipsink whip-endpoint=$WHIP

For the WHEP pipeline, at first, it was giving the following error for audio.

Unexpected response: 406 - cannot satisfy playback request: requesting non-existent audio track

Resolved the above issue by removing the audio caps from the pipeline but started getting the following error with the transceiver

WHEP Pipeline

gst-launch-1.0 whepsrc whep-endpoint=$WHEP video-caps="application/x-rtp,payload=101,encoding-name=VP8,media=video,clock-rate=90000" ! rtpvp8depay ! vp8dec ! videoconvert ! autovideosink

Not sure what causing this issue with whepsrc, I have tried the online WHEP player here and the video is getting played seamlessly.
