Unable to Load ROS2 bridge extension

[Jellal-17]

Hello, I am trying to use this repository through the Isaaclab version, I have previously installed Isaaclab and am using it for another project already. So, I followed all the instructions in the readme but I'm encountering this error no matter what I do.

2024-10-03 10:22:25 [16,294ms] [Error] [omni.ext.plugin] Failed to resolve extension dependencies. Failure hints: Can't find extension with name: omni.isaac.ros2_bridge Available versions: (none found) Synced registries:

Perhaps the extension 'omni.isaac.ros2_bridge' is not loaded?

If I comment the following, though the app is loading, the extension seems to persist.

"for i in range(env_cfg.scene.num_envs): create_front_cam_omnigraph(i)"

Can anyone help me with this or did I do anything wrong while Installing it ?

Hello, it looks like an installation problem with venv, can you please double-check it with readme instructions?

Yes, there was some issue with the installation of the Isaac Sim 4.2 app a couple of days ago, the "exts" folder was completely empty so I copied the files from 4.1 but didn't work. I have deleted all of my installations of isaaclab, Isaac sim and installed it again, now there is no similar issue, they might have fixed it now, thank you.
