How do you use ajv with references?

Hi,

Sorry for the dumb question but I'm struggling a bit to use this package. I'm exporting multiple Typescript interface, so I end up with a file like this:

{
  "definitions": {
    "Test1": {
      "type": "object",
      "properties": {
        "nested": {"$ref": "#/definitions/Test2"}
      },
      "required": [ "nested" ],
      "additionalProperties": false
    },
    "Test2": {
      "type": "object",
      "properties": {
        "title": { "type": "string"}
      },
      "required": [ "title" ],
      "additionalProperties": false
    }
  }
}

However when it's time to actually use the json schema I'm lost. I tried using ajv but I'm failing to understand how to validate one interface with a Reference using this json schema. There is no documentation regarding this use case so I'm wondering.

const ajv = new Ajv({ allErrors: true, discriminator: true });
const validate = ajv.compile(jsonSchema); // the one above

// Validate against Test1
validate({ nested: { title: 'foobar' }}); 

Without a reference I can just load the schema with the appropriate key but when there is references it won't work

const ajv = new Ajv({ allErrors: true, discriminator: true });
const validate = ajv.compile(jsonSchema["definitions"]["Test2"]);

// Validate against Test2 directly
validate({ title: 'foobar' }); 

Is there any way to tell ajv to validate Test1 inside the schema? Or any other way to achieve that.

Thanks ☺️
