Bug when integrating with ATT&CK Website

So, this is a weird one. When I try to create my own technique and link it to the ICS domain and connect it to the initial access tactic, I receive the following error,

File "update-attack.py", line 229, in
ptr"run_module"
File "/home/yash/Downloads/attack-website-master/modules/techniques/init.py", line 32, in run_module
return (techniques.generate_techniques(), techniques_config.module_name)

return self._inner[key]
KeyError: 'domain'

Start with modules/techniques/techniques.py, especially generate_data_for_md around the reported KeyError, and trace how update-attack.py invokes it. Reproduce the custom technique using the ICS domain and initial access tactic, then determine why the generated technique lacks the expected domain data. Done means generation completes without the KeyError for this case.
