Can't clone voices in Node.js

[soylomass]

Using the clone method in Node.js to clone a voice, using a Blob for the voice clip, results in the following error:

[Cartesia] Error cloning voice FetchError: invalid json response body at https://api.cartesia.ai/voices/clone/clip reason: Unexpected token e in JSON at position 0
    at /Users/federico/Projects/miniapps-api/node_modules/node-fetch/lib/index.js:273:32
    at processTicksAndRejections (node:internal/process/task_queues:95:5)
    at VoiceService.create (/Users/federico/Projects/miniapps-api/src/api/voice/voice.service.ts:212:19)
    at VoiceController.create (/Users/federico/Projects/miniapps-api/src/api/voice/voice.controller.ts:89:12) {
  type: 'invalid-json'
}

After debugging, found out that the API was returning an string (the sdk is only coded to support json responses in the clone method):

'error parsing clip
'

I tried replicating your implementation, but using native Node fetch instead of the package you use (cross-fetch) and it worked, so the problem must be that library messing up with the file somehow.
