No PPIO API key was set.

Error message

No PPIO API key was set.

What it means

Configuration guard thrown by the PPIOLLM constructor: the PPIO provider was selected but the PPIO_API_KEY environment variable is empty/unset, so the PPIO inference endpoint cannot be authenticated against.

Solutions

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

Strategy: validation

When it happens

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

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