resolve LLM endpoint: %w

Error message

resolve LLM endpoint: %w

What it means

This error wraps a failure from llm.ResolveEndpoint during `ocr llm test`. Endpoint resolution combines the config file, environment variables, and provider presets to decide which LLM URL/model/credentials to use; if no usable endpoint can be derived, this error surfaces with the underlying cause wrapped via %w.

Solutions

1. Configure an LLM provider via `ocr config provider` and confirm the URL/model are saved.
2. Export the required API-key environment variable for your chosen provider.
3. Check the wrapped cause after 'resolve LLM endpoint:' — it states what could not be resolved (provider, URL, or credentials).
4. If using Bedrock, set AWS_REGION and valid AWS credentials.

Example fix

// before: config has no endpoint
[llm]
model = "gpt-4o"
// after
[llm]
url = "https://api.openai.com/v1"
model = "gpt-4o"

// before running llm test, ensure an endpoint can be resolved
if _, err := llm.ResolveEndpoint(cfgPath); err != nil {
    fmt.Println("LLM endpoint not configured:", err)
    os.Exit(1)
}

ep, err := llm.ResolveEndpoint(cfgPath)
if err != nil {
    return fmt.Errorf("resolve LLM endpoint: %w — run 'ocr config provider' to configure", err)
}

When it happens

Trigger: Running `ocr llm test` when llm.ResolveEndpoint(cfgPath) fails: no provider or manual URL configured, required API-key env vars missing, or an unsupported/unknown provider value in the config.

Common situations: Fresh install with no config filled in; missing OPENAI_API_KEY / ANTHROPIC_API_KEY style env vars; typo'd provider name in config; config sets Bedrock but AWS credentials/region are absent.
