Codegen generating nullable while OpenAPI spec doesn't define nullable

[michel-jump]

The OpenAPI spec:

"TestEntityDto": {
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "format": "uuid"
    },
    "name": {
      "type": "string",
      "nullable": true
    },
    "created": {
      "type": "string",
      "format": "date-time"
    },
    "lastModified": {
      "type": "string",
      "format": "date-time"
    }
  },
  "additionalProperties": false
},

The generated type:

export type TestEntityDto = {
  id?: string;
  name?: string | null;
  created?: string;
  lastModified?: string;
};

Why is the id nullable?

It's not nullable, it's optional, because you didn't mark it as required: https://swagger.io/docs/specification/v3_0/data-models/data-types/#objects
