@danktec what is OMNICONFIG set to? Can you include the file contents too please?

Greetings! Yeah, thats a bug which should be fixes by this PR, but it actually hides some other error.

[DmitriyMV]

Not exactly closed, since we don't know the underlying error.

Getting the same error.
omnictl is installed on Ubuntu
omnictl version v0.43.3 (API Version: 1)
omniconfig.yaml placed in this path ~/.config/omni/config/omniconfig.yaml.
Configuration is correct; the same works correctly on macOS

If someone following this post to install and configure omnictl just use this command:
export OMNICONFIG=~/.config/omni/config/omniconfig.yaml

@mrkhachaturov Something is wrong. The stacktrace you show is from omnictl 0.42.0. Could you double check pls?

This issue arises when you follow the instruction to Install and Configure Omnictl.

We must first define the OMNICONFIG path.
When I define export OMNICONFIG=~/.config/omni/config/omniconfig.yaml, everything worked as expected.

The merge functionality is also working after defining OMNICONFIG

I have made PR to include this in documantation.
