Summary: array field has no items type declared

What this means

A field is declared with type: array but has no items: attribute. Shaperail needs the element type to generate the correct Rust Vec<T> type, the SQL column type, and the OpenAPI schema.

Example that triggers this

resource: items
version: 1
schema:
  id:   { type: uuid, primary: true, generated: true }
  tags: { type: array }

How to fix it

Add items: <element_type> to the array field:

tags: { type: array, items: string }
