{path} requires at least {profile.min_condition_count} entri

Error message

{path} requires at least {profile.min_condition_count} entries for task {profile.task!r}, got {len(conditions)}

What it means

The task profile sets a min_condition_count higher than 1 and fewer entries were supplied — e.g. first/multi-frame tasks that need N keyframes.

Solutions

1. Supply at least min_condition_count condition entries
2. Check the task profile's min_condition_count and enforce it in the client UI

Example fix

// before
"conditions": [kf0]
// after
"conditions": [kf0, kf1]

if profile.min_condition_count and len(conditions) < profile.min_condition_count:
    raise ValueError('too few conditions')

When it happens

Trigger: Sending 1 condition to a task whose profile.min_condition_count is 2 or more.

Common situations: Multi-keyframe storyboard tasks where the client only uploads the first frame; partial upload failures silently dropping entries.
