When does this happen?

IF When using Ollama as LLM provider, a 'KeyError: key_name' occurs during crew initialization because the 'ollama' entry in ENV_VARS lacks a 'key_name' for 'API_BASE'.

How others solved it

THEN Add an entry for 'ollama' in the ENV_VARS dictionary with a key_name for 'API_BASE'. The workaround is to import ENV_VARS from crewai.cli.constants and update it with the required mapping before importing the crew. Ensure the .env file includes API_BASE=http://site_1:11434.

from crewai.cli.constants import ENV_VARS
ENV_VARS.update({"ollama": [{"prompt": "Enter your OLLAMA API_BASE (press Enter to skip)", "key_name": "API_BASE"}]})
