error 401

[spark widget]

I keep getting this error and I have been trying to debug this for like 2 hours. THis is the console after I added all the debugging while trying to figure it out.

Voice generation requested for channel 1399854698349072534

I am testing it out on the free plan.

Hey @spark widget - sorry idk how we missed this earlier that's our bad. What's the specific API you're trying to hit?

[spark widget]

hello- thanks for replying!

API Endpoint:

POST https://api.cartesia.ai/tts/bytes

Headers Used:

Cartesia-Version: 2024-06-10
X-API-Key: [my_key]
Content-Type: application/json
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36

Request Body:

  {
    "model_id": "sonic-2",
    "transcript": "text to speak",
    "voice": {
      "mode": "id",
      "id": "b4583c6e-790d-43fa-ae06-0d8ec09c3c84"
    },
    "output_format": {
      "container": "wav",
      "encoding": "pcm_f32le",
      "sample_rate": 44100
    },
    "language": "en",
    "speed": "normal"
  }

The Issue is that the code works in the playground when i tried it out but returns 401 Invalid token when called programmatically, even though the API key is valid - i double checked it a bunch of times

@spark widget could you share the code snippet you're using to hit the bytes endpoint?

[spark widget]

  async def _generate_cartesia_voice(self, text: str) -> Optional[bytes]:
