Running Generate From Schema on a Model with a unique array constraint of enums causes Stoplight to hang

[pazaan]

Given the following model:

{
  "type": "object",
  "title": "New User Details",
  "properties": {
    "username": {
      "type": "string",
      "format": "email"
    },
    "emails": {
      "type": "array",
      "items": {
        "anyOf": [
          {
            "format": "email"
          }
        ],
        "type": "string"
      }
    },
    "password": {
      "type": "string",
      "format": "password"
    },
    "roles": {
      "type": "array",
      "items": {
        "anyOf": [
          {
            "enum": [
              "clinic"
            ]
          }
        ],
        "type": "string"
      }
    }
  },
  "required": [
    "username",
    "emails",
    "password",
    "roles"
  ]
}

If I have a PATH that takes a Request Body that is a $ref to the model, and push the Generate From Schema button, an example is generated exactly as I expect it to be (albeit with duplicates).

If I change the model to the following:

{
  "type": "object",
  "title": "New User Details",
  "properties": {
    "username": {
      "type": "string",
      "format": "email"
    },
    "emails": {
      "type": "array",
      "uniqueItems": true,
      "items": {
        "anyOf": [
          {
            "format": "email"
          }
        ],
        "type": "string"
      }
    },
    "password": {
      "type": "string",
      "format": "password"
    },
    "roles": {
      "type": "array",
      "items": {
        "anyOf": [
          {
            "enum": [
              "clinic"
            ]
          }
        ],
        "type": "string"
      }
    }
  },
  "required": [
    "username",
    "emails",
    "password",
    "roles"
  ]
}

Then the example is still generated as expected (still with potentially duplicate roles).

If I use the following model:

{
  "type": "object",
  "title": "New User Details",
  "properties": {
    "username": {
      "type": "string",
      "format": "email"
    },
    "emails": {
      "type": "array",
      "uniqueItems": true,
      "items": {
        "anyOf": [
          {
            "format": "email"
          }
        ],
        "type": "string"
      }
    },
    "password": {
      "type": "string",
      "format": "password"
    },
    "roles": {
      "type": "array",
      "uniqueItems": true,
      "items": {
        "anyOf": [
          {
            "enum": [
              "clinic"
            ]
          }
        ],
        "type": "string"
      }
    }
  },
  "required": [
    "username",
    "emails",
    "password",
    "roles"
  ]
}

Pressing Generate From Schema now causes Stoplight Next to hang. This happens both in the Desktop app, and on the website.
