Ok added a conditional check in agent.py to skip processing key_name unless it exists. This prevents the error and ensures compatibility for setups where key_name is not required.

Proposed Fix: A conditional check can be added in agent.py to skip processing key_name unless it's present and valid:

if "key_name" in env_var and env_var["key_name"] in unnacepted_attributes:
continue

This ensures the error doesn’t occur when key_name is absent but unnecessary for the task.
