Unable to Create File from R2 to Openai

Following these directions, I'm not able to get create file to work. https://developers.cloudflare.com/workers/tutorials/create-finetuned-chatgpt-ai-models-with-r2/ I'm getting "400 'file' is a required property". Here is my code:

await env.DOC_BUCKET.put(id, trainingStr);

const obj = await env.DOC_BUCKET.get(id);

const blob = await obj.blob();
const file = await toFile(blob, obj.key);

const fileCreationResponse = await openai.files.create({
  file,
  purpose: "fine-tune",
});

await env.DOC_BUCKET.put(id, trainingStr);

const obj = await env.DOC_BUCKET.get(id);

const blob = await obj.blob();
const file = await toFile(blob, obj.key);

const fileCreationResponse = await openai.files.create({
  file,
  purpose: "fine-tune",
});
