Can't create a proper typescript classes out of the following schema

[manuelarte]

So I have the following schema (I don't have control over it, so I can't change it):

{

  "name": "mySchema",
  "namespace": "com.manuelarte",
  "doc": "Create, update or delete a VM resource",

      ],

But when I try to generate the typescript classes with:

import { toTypeScript } from '@ovotech/avro-ts';
import * as fs from "node:fs";

const avro = fs.readFileSync("./resources/schema/myschema.avsc", { encoding: 'utf8', flag: 'r' });
export const ts = toTypeScript(avro, { withTypescriptEnums: true });
console.log(ts)

I get, an output that it's not correct, starting with:

export type , GB or MB",
                      "default": null
                    }
                  ]
                }
              ],
              "doc": "Memory information, including amount, type, and size unit",
              "default": null
            }
          ]
        }
      ],
      "doc": "System configuration: cpu and memory",
      "default": null
    }
...

am I doing something wrong?
