SDK Fails to Parse NDJSON Format in Vectorize Upsert, Works with Fetch

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

When using the Cloudflare TypeScript SDK to perform a Cloudflare Vectorize upsert operation, I encounter the following error:

Error: 400 {"result":null,"success":false,"errors":[{"code":40023,"message":"vectorize.upstream_error - failed to parse upsert vectors request in ndjson format: line Some(0) was not expected format"}],"messages":[]}

This error happens when I call the client.vectorize.indexes.upsert method. However, the same request works fine when using the fetch method directly, with the same body and headers.

It seems that the SDK might not be properly formatting the request in the expected ndjson format.

To Reproduce

1. Use the Cloudflare TypeScript SDK to perform a vectorization upsert using the client.vectorize.indexes.upsert method.
2. See the error failed to parse upsert vectors request in ndjson format: line Some(0) was not expected format.
3. Switch to using the fetch method with the same body and headers.
4. The request works as expected without the error.

Code snippets

const vectors = [
    { id: "1", values: [...], metadata: { columnId: 1 } },
    { id: "2", values: [...], metadata: { columnId: 1 } },
  ];

  const body = vectors
    .map((vector) => JSON.stringify(vector))
    .join("\n")
    .trim();

  const client = new Cloudflare({
    apiToken: env.CLOUDFLARE_VECTORIZE_API_TOKEN,
  });

  const insertUsingSdk = await client.vectorize.indexes.upsert(
    index.name,
    {
      account_id: env.CLOUDFLARE_ACC_ID,
      body: body,
    },
    {
      headers: {
        "Content-Type": "application/x-ndjson",
      },
    },
  );

  const insertUsingFetch = await fetch(
    `https://api.cloudflare.com/client/v4/accounts/${env.CLOUDFLARE_ACC_ID}/vectorize/v2/indexes/${index.name}/insert`,
    {
      method: "POST",
      body: body,
      headers: {
        Authorization: `Bearer ${env.CLOUDFLARE_VECTORIZE_API_TOKEN}`,
        "Content-Type": "application/x-ndjson",
      },
    },
  );
