Summary: format attribute used on non-string field

What this means

A field has a format: attribute (e.g., format: email) but its type is not string. The format attribute is only meaningful on string fields and controls validation and OpenAPI schema output.

Example that triggers this

resource: items
version: 1
schema:
  id:  { type: uuid, primary: true, generated: true }
  age: { type: integer, required: true, format: email }

How to fix it

Change the field type to string, or remove the format attribute from the field.
