I keep getting the 'Anthropic is not a constructor' error, and the Client is not functioning properly.

I have tried repeatedly, but strangely, I can't reference the Client class. So, I directly called the Client to make requests, but I received a 404 error, and it is not functioning properly. In my view, it's odd that there is no reference at all.

const Anthropic = require("@anthropic-ai/sdk");
console.log("Anthropic: ", Anthropic);

const anthropic = new Anthropic({
  apiKey: process.env["ANTHROPIC_API_KEY"], // This is the default and can be omitted
});

async function main() {
  const message = await anthropic.messages.create({
    max_tokens: 1024,
    messages: [{ role: "user", content: "Hello, Claude" }],
    model: "claude-3-opus-20240229",
  });

  console.log(message.content);
}

main();

Anthropic:  {
  HUMAN_PROMPT: '\n\nHuman:',
  AI_PROMPT: '\n\nAssistant:',
  Client: [class Client]
}
