Jimeng submit returned no task_id: {data}

Error message

Jimeng submit returned no task_id: {data}

What it means

Raised when the Jimeng (Volcengine CVSync2AsyncSubmitTask) submit call succeeds at the HTTP and code level but the response's data.task_id is missing. The async flow needs the task_id to poll CVSync2AsyncGetResult; without it the tool raises RuntimeError with the full response body so you can see what came back instead.

Solutions

1. Inspect the {data} in the error message to see the actual envelope and any status/message fields inside data.
2. Verify the Volcengine account has Jimeng video generation enabled and is not out of quota.
3. Confirm access key / secret key pair is valid and the system clock is in sync (signature includes timestamps).
4. Update OpenMontage or check Jimeng docs if the response contract (data.task_id) changed.

import os

for var in ("JIMENG_ACCESS_KEY", "JIMENG_SECRET_KEY"):
    if not os.environ.get(var):
        raise RuntimeError(f"{var} not set — Jimeng submit will fail")

try:
    result = jimeng_video(inputs)
except RuntimeError as e:
    if "no task_id" in str(e):
        # inspect embedded body; do not blind-retry a contract/auth problem
        raise ProviderContractError(str(e)) from e
    raise

When it happens

Trigger: POST to CVSync2AsyncSubmitTask returns JSON without data.task_id — e.g. req_key not matching a valid video capability, signature/canonical-request issues that pass code checks but route wrong, or an API revision changing the response envelope.

Common situations: Invalid or outdated _REQ_KEY_VIDEO after Jimeng API updates; a signing bug (HMAC of body/query) causing a structured-but-empty data object; account not entitled to the video generation capability, returning an error shape the code check does not recognize.
