json-schema-faker and nullable type

[dephiros]

I start to adopt this library inside our company and one of the usage is to generate fixture for testing from JSON Schema
One of the field that I am struggling with is nullable field. Ex:

const ObjSchema = Type.Object({
  firstName: Type.String({
    faker: 'name.firstName',
  }),
  lastName: Type.Union([
    Type.String({
      faker: 'name.lastName'
    }),
    Type.Null()
  ])
});

which would generate this schema:

{
  "type": "object",
  "properties": {
    "firstName": {
      "type": "string",
      "faker": "name.firstName"
    },
    "lastName": {
      "anyOf": [
        {
          "type": "string",
          "faker": "name.lastName"
        },
        {
          "type": "null"
        }
      ]
    }
  }
}

which makes sense to me. The problem is that json-schema-faker does not seem to understand anyOf but understand type: ["string", "null"] which I also see as a valid way to represent nullable string according to JSON Schema.

Any suggestion to handle this case nicely from Typebox's end? This might be a problem with json-schema-faker or we just have to preprocess the fixture manually

Closed since it was my mistake that cause it not to work!
