RTPBin issue?

[scraper]

Hey,

I'm attempting to stream video/audio through gstreamer and I tried
replicating the code used in this example
https://github.com/versatica/mediasoup-demo/blob/v3/broadcasters/gstreamer.sh
however, I seem to be getting an error with this command.

<nabbled_embed>
gst-launch-1.0 -v pulsesrc ! queue ! audioconvert ! decodebin !
audioresample ! audioconvert ! audio/x-raw,channels=2,rate=24000 ! opusenc !
rtpopuspay pt=101 ssrc=11111111 ! rtpbin.send_rtp_sink_1 
rtpbin.send_rtp_src_1 ! udpsink host=rtc-eu-2.giggl.app port=40606
rtpbin.send_rtcp_src_1 ! udpsink host=rtc-eu-2.giggl.app port=43353
sync=false async=false
</nabbled_embed>
I seem to be getting

<nabbled_embed>
WARNING: erroneous pipeline: No sink-element named "(null)" - omitting link
</nabbled_embed>

I've boiled this down to the exact line <nabbled_embed>!
rtpbin.send_rtp_sink_1</nabbled_embed>
 I believe this is the crux of the problem but I'm unsure why? Any help is
greatly appreciated <3
