Error message

{path} must be empty for task {profile.task!r} (got {len(conditions)} entries)

What it means

The task's profile does not accept conditions (conditions_required false) but the request supplied a non-empty list. Tasks like plain t2v reject any condition entries.

Solutions

1. Remove the conditions list (or pass []) for this task
2. Switch to a task whose profile permits conditions if conditioning is required

Example fix

// before
"conditions": [{"role": "reference", ...}]  # on a no-conditions task
// after
"conditions": []

if not profile.conditions_required:
    request['conditions'] = []

When it happens

Trigger: Sending a keyframe/reference condition to a task that takes only text.

Common situations: Reusing a ref2va/i2v request body for a text-only task; conditioning pipeline always attaching reference images.
