OpenRouter response is empty.

Error message

OpenRouter response is empty.

What it means

openrouter_fn checks the chat completion response for None and raises 'OpenRouter response is empty.' if the SDK returned nothing. This guards against OpenRouter silently returning an empty object instead of a normal choices payload.

Solutions

1. Verify the model slug in config.ini exists on openrouter.ai/models
2. Check your OpenRouter account balance/credits and API key validity
3. Retry after a short delay if OpenRouter is having an outage (status.openrouter.ai)
4. Wrap the call so None is handled explicitly and a fallback model can be used

Example fix

// before
model = "openai/gpt-4-32k"  # removed slug -> empty response
// after
model = "openai/gpt-4o"  # current valid slug

def openrouter_ready(api_key, model):
    import os, requests
    if not api_key or not os.getenv('OPENROUTER_API_KEY'):
        return False
    r = requests.get('https://openrouter.ai/api/v1/models', timeout=10)
    return r.ok and any(m['id'] == model for m in r.json().get('data', []))

def has_choices(resp):
    return resp is not None and getattr(resp, 'choices', None) and resp.choices[0].message.content is not None

try:
    out = provider.openrouter_fn(history)
except Exception as e:
    if 'response is empty' in str(e):
        log.warning("OpenRouter returned empty response; check model slug and credits")
    raise

When it happens

Trigger: client.chat.completions.create(...) returns None — typically when OpenRouter returns an empty body, the requested model is unavailable/deprecated and routed to nothing, or the account has no credits and the relay returns an empty 200.

Common situations: OpenRouter model slug invalid or removed; free-tier model temporarily unavailable; account out of credits so the relay yields an empty response; transient OpenRouter outage returning empty bodies.
