No task_id in response: {json.dumps(data, indent=2)}

Error message

No task_id in response: {json.dumps(data, indent=2)}

What it means

After create_task() gets HTTP 200 and base_resp OK, it expects a task_id in the JSON. If absent, the response shape is unexpected — an API revision change, a proxy/gateway wrapper, or an error returned without a base_resp block. The full JSON is dumped to aid diagnosis.

Solutions

1. Inspect the dumped JSON keys — they reveal whether the endpoint/contract changed.
2. Confirm API_BASE ends in /v1 and points to the correct region for the key.
3. Retry once; transient gateway wrappers sometimes intercept individual calls.

Example fix

# before
task_id = create_task(prompt=p, model=m)

# after - guard the contract before trusting the value
data = resp.json()
task_id = data.get('task_id')
if not task_id:
    # log full body, fall back to alternate key if API changed
    task_id = data.get('id') or data.get('task', {}).get('id')
    if not task_id:
        raise RuntimeError(f'unexpected response: {data}')

def has_task_id(resp_json: dict) -> bool:
    return bool(resp_json.get('task_id'))
# after the POST, before relying on it:
if not has_task_id(data):
    raise RuntimeError(f'no task_id: {data}')

def is_task_response(d) -> bool:
    return isinstance(d, dict) and isinstance(d.get('task_id'), str) and bool(d['task_id'])

try:
    task_id = create_task(prompt=p, model=m)
except SystemExit as e:
    raise RuntimeError(f'create_task returned no task_id: {e}') from e

When it happens

Trigger: POST video_generation returns 200 with valid base_resp but no task_id key — e.g. API_BASE points to the wrong version path, a proxy wraps/renames the response, or a new API revision changed the contract.

Common situations: API_BASE missing the /v1 suffix or pointing to the wrong region; corporate proxy rewrites the body; SDK called against a newer/older API version than the script targets.
