No Z.AI API key was set.

Error message

No Z.AI API key was set.

What it means

Configuration guard thrown by the ZAiLLM constructor: the Z.AI provider was selected but the ZAI_API_KEY environment variable is empty/unset, so requests to api.z.ai cannot be authenticated and the client refuses to construct.

Solutions

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

Strategy: validation

When it happens

Trigger: Thrown at provider construction when no Z.AI API key is configured.

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