'blob' is not a valid value for binaryType

[SalamanderXing]

What version of Bun is running?

1.2.2

What platform is your computer?

Darwin 24.3.0 arm64 arm

What steps can reproduce the bug?

Install:

bun install @cartesia/cartesia-js

Run the following code with Bun:

import { CartesiaClient } from "@cartesia/cartesia-js";

const cartesia = new CartesiaClient({
  apiKey: process.env.CARTESIA_API_KEY,
});

// Initialize the WebSocket. Make sure the output format you specify is supported.
const websocket = cartesia.tts.websocket({
  container: "raw",
  encoding: "pcm_f32le",
  sampleRate: 44100,
});
// const websocket = cartesia.tts.websocket({
//   container: "raw",
//   encoding: "mp3",
//   sampleRate: 44100,
// });

try {
  await websocket.connect();
} catch (error) {
  console.error(`Failed to connect to Cartesia: ${error}`);
  throw error;
}

// Create a stream.
const response = await websocket.send({
  modelId: "sonic-english",
  voice: {
    mode: "id",
    id: "a0e99841-438c-4a64-b679-ae501e7d6091",
  },
  transcript: "Hello, world!",
  // The WebSocket sets output_format on your behalf.
});

// Access the raw messages from the WebSocket.
response.on("message", (message) => {
  // Raw message.
  console.log("Received message:", message);
});

// You can also access messages using a for-await-of loop.
for await (const message of response.events("message")) {
  // Raw message.
  console.log("Received message:", message);
}

What is the expected behavior?

running the same file with Node:

Additional information

You need a CARTESIA_API_KEY (you can get it for free: https://cartesia.ai/) in your environment but it should be possible to reproduce the error without it as well.
