Fix example for creating new version using `workers.scripts.versions.create`

[huv1k]

Confirm this is a Typescript library issue and not an underlying Cloudflare API issue

• This is an issue with the Typescript library

Describe the bug

Currently there is no clear way how to upload scripts using SDK. I was trying to use workers.scripts.versions.create methods, but there is clearly missing uploading actual scripts. When trying basic example:

async function deploy() {
  const client = new Cloudflare({
    apiToken: "****",
  });

  const version = await client.workers.scripts.versions.create("worker", {
    account_id: "****",
    metadata: {
      main_module: "index.js",
    },
  });

  console.log(version);
}

deploy().catch(console.error);

This always throws 400 with {"code":10021,"message":"could not read content for part metadata"}. Looking on various support forum there is issue with compatibility_date. Even setting this doesn't fix it I tried to add script content and metadata to body, but same result. Could you please provide clearer guidance in example how to create a new version? We want to use this to create gradual deployment programatically.

To Reproduce

1. Create script

async function deploy() {
  const client = new Cloudflare({
    apiToken: "****",
  });

  const version = await client.workers.scripts.versions.create("worker", {
    account_id: "****",
    metadata: {
      main_module: "index.js",
    },
  });

  console.log(version);
}

deploy().catch(console.error);

2. Add correct apiToken and account_id
3. Run it node index.js
4. There is error printed in terminal

Hi @huv1k the next release will have a fix for versions create. The interface will look like this:

import Cloudflare from 'cloudflare';
import { toFile } from 'cloudflare/index';

const client = new Cloudflare({
  apiToken: "replace-me",
});

const scriptContent = `
  export default {
    async fetch(request, env, ctx) {
      return new Response("Hello world!", { status: 200 });
    }
  };
`;

const script = await client.workers.scripts.versions.create("worker", {
  account_id: "123456789",
  metadata: {
    main_module: "worker.mjs",
  },
  files: [
    await toFile(
      Buffer.from(scriptContent),
      "worker.mjs",
      {
        type: "application/javascript+module",
      }
    )
  ]
});
