Conflicting sound_end_time values between top-level input an

Error message

Conflicting sound_end_time values between top-level input and face_choose[0]

What it means

Raised by KlingLipSyncTool._copy_timing_fields when sound_end_time is provided both at the top level and in face_choose[0] with different int values. Same fail-fast contract as the other timing fields: the tool will not arbitrate between two conflicting crop-end values.

Solutions

Delete the top-level sound_end_time and keep it only in face_choose[0] (per-face is more precise)
Or align both values to the same number of milliseconds
Grep your payload builder for double-injection of sound_end_time

Example fix

# before
inputs = {"sound_end_time": 6000, "face_choose": [{"face_id": "f1", "sound_end_time": 5000}]}

# after
inputs = {"face_choose": [{"face_id": "f1", "sound_end_time": 5000}]}

Defensive patterns

Strategy: validation

Validate before calling

face_item = (inputs.get("face_choose") or [{}])[0]
for key in ("sound_end_time",):
    nested, top = face_item.get(key), inputs.get(key)
    if nested is not None and top is not None and int(nested) != int(top):
        raise ValueError(f"conflicting {key}: pick one scope")

Prevention

Set sound_end_time only in face_choose for multi-face jobs
Remove stale top-level timing fields when adding per-face overrides
Validate both scopes for equality before calling

When it happens

Trigger: advanced_lip_sync with inputs['sound_end_time']=6000 and face_choose=[{'face_id': 'f1', 'sound_end_time': 5000}].

Common situations: Face-specific end times were tuned while an old top-level sound_end_time remained in the payload; defaults injected by a wrapper at the top level colliding with per-face values authored later.
