Invalid YAML

steps[0].type: must be one of: http, db, shell, print, loop, call, if

​

What It Checks

• Required fields — name, step type, step name uniqueness
• Step type-specific fields — HTTP needs request block, shell needs command, etc.
• Mutually exclusive fields — e.g., query and command on DB steps, request and db on HTTP steps
• Timeout formats — Validates duration strings like 30s, 5m
• Loop foreach format — Must be list, item
• If condition format — Must be [path, op, value] (3 elements)
• Assert/Extract — Checks for empty keys and paths
• Unknown fields — Rejects YAML keys that do not match the schema
