API base path must be provided to use agents.

Error message

API base path must be provided to use agents.

What it means

Setup guard in checkSetup(): provider is 'generic-openai' but GENERIC_OPEN_AI_BASE_PATH is unset. Generic OpenAI-compatible endpoints have no default URL, so a base path must be supplied or agent setup fails.

Solutions

  1. Set the GENERIC_OPEN_AI_BASE_PATH environment variable.
  2. Ensure the OpenAI-compatible endpoint is reachable.
Defensive patterns

Strategy: validation

When it happens

Trigger: A generic OpenAI-compatible agent provider was selected but no API base path is configured.

Common situations: This error is raised at runtime in server/utils/agents/index.js. It occurs when the required configuration for this provider is missing or invalid (unset environment variables, empty API key or base path), when the external service is unreachable or returns an unexpected response, or when invalid input reaches the call site. To prevent it, validate the relevant provider settings and environment variables at startup and confirm the service is reachable before this code path executes.
