GstRav1Enc panicking on wrong bitrate type (expected gint, got guint)

Upon running the commands according to the example,

gst-launch-1.0 webrtcsink name=ws meta="meta,name=gst-stream" videotestsrc ! ws. audiotestsrc ! ws. or

gst-launch-1.0 -v \   videotestsrc ! video/x-raw,width=640,height=480,framerate=30/1 ! \   webrtcsink stun-server=stun://stun.l.google.com:19302 signaller::uri=ws://<your-signaling-server>:8443

I got the following error with type mismatch panick:

thread 'tokio-runtime-worker' panicked at net/webrtc/src/webrtcsink/imp.rs:777:21:
property 'bitrate' of type 'GstRav1Enc' can't be set from the given type (expected: 'gint', got: 'guint')

While I was able to get the stream running (as seen in the end), the signaling server doesn't show anything to indicate that the webrtcsink is connected.
