I have tried to Generate Extension tool to create a webrtcsink component for the Graph Composer. webrtcsink is a Gstreamer element under the rswebrtc plugin. Since this plugin is not installed and builded inside the deepstream 8.0-gc-triton-devel container I have done this proccess succesfully. Also I am able to view webrtcsink via gst-inspect-1.0 command.
When I press install dependencies button I am observing following error logs.
[Error] [asyncio] Task exception was never retrieved

But when I install dependencies by using following commands there is no error showing up.
cd /opt/nvidia/graph-composer/extension-dev
./install_dependencies.sh --allow-root
After that I am clicking Generate button and everything seems to be fine. However, when I click the Build button following error logs are popping up.

That is why I tried to build manually by using following command. (Inside the Target Outpu Directory)
bazel build //extensions/rswebrtc:register_rswebrtc_ext
But following error is seems to be main problem

Also I have changed WORKSPACE file because the generated one wer not including @rules_python and @bazel_skylib dependencies.
I am also attaching my WORKSPACE file.
WORKSPACE.txt (2.1 KB)
My question is what I have done wrong while generating a component.
