When does this happen?
IF When creating an auto router in LiteLLM with missing optional or mandatory fields, the error 'Cannot destructure property litellmParamsObj of a[0] as it is undefined' occurs.
How others solved it
THEN Ensure all required and optional fields (e.g., model name, API key, deployment parameters) are fully specified when initializing a LiteLLM router. Missing fields cause the router to attempt destructuring an undefined array element, which raises this error. Populating all configuration fields resolves the issue.
router = Router(model_list=[{'model_name': 'gpt-4', 'litellm_params': {'model': 'gpt-4', 'api_key': 'sk-...'}}])Related patterns
