Problem description

Assuming the language in API Design Guidelines is normative, CAMARA_common.yaml ErrorInfo format is incorrectly/unnencessarily requiring all the properties of ErrorInfo schema.

ErrorInfo:
   type: object
   required:
    - message
    - status
    - code
   properties:
    message:
     type: string
     description: A human readable description of what the event represent
    status:
     type: integer
     description: HTTP response status code
    code:
     type: string
     description: Friendly Code to describe the error

Expected behavior

Per DG, no field should be listed as required.

Alternative solution

Explicitly state which fields, if any, are required in Design Guideline and update, as necessary, the CAMARA_common.yaml to match definition.
