No CometAPI API key was set.

Error message

No CometAPI API key was set.

What it means

Constructor guard in CometApiLLM: the COMETAPI_LLM_API_KEY (or equivalent) environment variable is unset, so the CometAPI client cannot be authenticated and provider construction fails before any model or chat operation.

Solutions

  1. Set the CometAPI API key in provider settings or env.
Defensive patterns

Strategy: validation

When it happens

Trigger: Thrown at provider construction when no CometAPI key is configured.

Common situations: CometAPI selected as LLM provider without an API key.
