Sonilo generation error ({code}): {message}

Error message

Sonilo generation error ({code}): {message}

What it means

Raised while consuming the Sonilo NDJSON event stream when an event of type "error" arrives. The stream itself is healthy (HTTP 200); the server reports an in-generation failure with a code and message which the node surfaces verbatim before any audio completes. Malformed JSON lines are skipped with a warning, so this only fires on well-formed error events.

Solutions

1. Read the code/message: content-related codes need a prompt change, quota codes need billing/top-up
2. Retry once for transient internal errors (UNKNOWN/code not matching known categories)
3. Check Sonilo account status and remaining credits

try:
    audio = await _sonilo_generate(...)
except Exception as e:
    msg = str(e)
    if "Sonilo generation error" in msg:
        code = msg.split("(")[1].split(")")[0]
        if code in ("QUOTA", "RATE_LIMIT"):
            schedule_retry_later()
        else:
            raise ValueError(f"Prompt rejected by Sonilo: {msg}") from e
    else:
        raise

When it happens

Trigger: POST succeeds, streaming begins, and the server emits {"type":"error","code":...,"message":...} mid-stream — e.g. content policy rejection, internal model failure, or quota exhaustion during music generation.

Common situations: Prompt content rejected by Sonilo moderation; account quota/credits exhausted mid-request; Sonilo model-side errors occurring after queueing.
