Solutions

1. Set `step_status` to one of: not_started, in_progress, completed, blocked.
2. Omit `step_status` entirely if you only want to update step_notes.

When it happens

Trigger: Raised when `mark_step` is called with a `step_status` value outside the allowed set: not_started, in_progress, completed, blocked.

Common situations: See trigger scenarios.
