Hi @zulfadleemohd1997 - The error message indicates that the Python module omni.replicator.core failed to import due to an issue with the urllib3 package, specifically it’s unable to import DEFAULT_CIPHERS from urllib3.util.ssl.

This could be due to a few reasons:

  1. The urllib3 package might not be installed or might be improperly installed. You can try reinstalling it using the omni.kit.pipapi extension as shown in the code snippet from the Omniverse Kit Documentation:
# omni.kit.pipapi extension is required
import omni.kit.pipapi

omni.kit.pipapi.install(
    package="urllib3",
    version="1.26.7",  # replace with the version you need
    module="urllib3", 
    ignore_import_check=False,
    ignore_cache=False,
    use_online_index=True,
    surpress_output=False,
    extra_args=[]
)
  1. There might be a version mismatch between urllib3 and other packages. Ensure that you have compatible versions of all your packages.
  2. The DEFAULT_CIPHERS attribute might not be available in the version of urllib3 you are using. You might need to upgrade or downgrade urllib3 to a version that includes this attribute.

I’m having the same issue on Ubuntu 22.04 using Isaac Sim 2022.2.1. Up-/Downgrading urllib3 results in dependency issues with botocore and google auth and then changing their version leads down a whole new depedency rabbithole.
