No taskId in Suno response: {data}

Error message

No taskId in Suno response: {data}

What it means

Raised by SunoTool after a successful HTTP POST to the Suno API when neither data.data.taskId nor data.taskId is present in the JSON response. The generation task was never created, so there is nothing to poll. It usually means the third-party Suno gateway returned an error payload or auth/quota message with HTTP 200, or the gateway's response schema differs from what this client expects.

Solutions

1. Inspect the full response body included in the message — it states exactly what the gateway returned (auth error, quota, different schema).
2. Verify the Suno API key is valid and the account has generation credits.
3. Compare the returned JSON's task-id field name against data.data.taskId / taskId and add the correct key to the extraction in _create.
4. Confirm the gateway base URL matches the provider documented for this tool version.

Example fix

// before
task_id = data.get("data", {}).get("taskId") or data.get("taskId")

// after (tolerate alternate schemas)
task_id = (
    data.get("data", {}).get("taskId")
    or data.get("taskId")
    or data.get("data", {}).get("task_id")
    or data.get("task_id")
)
if not task_id:
    raise RuntimeError(f"No taskId in Suno response: {data}")

try:
    task_id = tool._create(payload, api_key)
except RuntimeError as e:
    if "No taskId" in str(e):
        # response body is embedded in the message; log it and check key/quota
        raise

When it happens

Trigger: POSTing a generate-music payload to a Suno-compatible gateway (api-key via Bearer token) where the response body contains an error object, a different key name for the task id, or an HTML/login page instead of JSON with a taskId.

Common situations: Invalid or expired Suno API key; gateway quota exhausted; using a Suno proxy whose response schema (e.g. data.data.taskId vs taskId vs clipId) differs by version; base URL pointing to the wrong endpoint.
