Repro

Running

convertTypeScriptToCoreTypes("export type Num = 1000 | -1")

produces the following ouput:

{
  "data": {
    "version": 1,
    "types": [
      {
        "name": "Num",
        "title": "Num",
        "type": "or",
        "or": [
          {
            "type": "number",
            "const": 1000,
            "title": "Num"
          }
        ]
      }
    ]
  },
  "convertedTypes": [
    "Num"
  ],
  "notConvertedTypes": []
}

when the correct output should be:

{
  "data": {
    "version": 1,
    "types": [
      {
        "name": "Num",
        "title": "Num",
        "type": "or",
        "or": [
          {
            "type": "number",
            "const": 1000,
            "title": "Num"
          },
          {
            "type": "number",
            "const": -1,
            "title": "Num"
          }
        ]
      }
    ]
  },
  "convertedTypes": [
    "Num"
  ],
  "notConvertedTypes": []
}
