Array null values

Hello,

 

Is it possible to define an array that can not contain null? 

I'm compiling it to Java with Open API 3.0

 

f.e for this example

A:
  type: array
  minItems: 1
  items:
    $ref: "#/components/schemas/B"
B: 
 type: string
 pattern: ^[a-z]+$

 I consider [null] or ["abc",null] invalid

 

Thanks in advance

    Hi radekoziol,

     

    Your example is correct. In OpenAPI 3.0, null values are only allowed if the schema has the nullable: true attribute. Since the B schema is not marked as nullable, it only allows string values but not nulls.
