API of Remix createfileUploadHandler to handle form errors

createfileUploadHandler-api.ts

// Documentation:
// https://remix.run/docs/en/v1/api/remix#unstable_createfileuploadhandler
const uploadHandler = unstable_createFileUploadHandler({
  maxFileSize: 5_000_000,
  file: ({ filename }) => filename
})

const fakeDb = createFakeDb()
export const action: ActionFunction = async ({ request }) => {
  const formData = await unstable_parseMultipartFormData(
    request,
    uploadHandler
  );

  // Pseudo code
  const avatarUrl = formData.get("avatar");
  const name = formData.get("name")
  const email = formData.get("email")
  
  // My question:
  // Image `fakeDb.users.create` returns an error because
  // email doesn't have an email format or `name` is empty.
  //
  // At this point we already uploaded `avatar` file to our server / s3 bucket?
  const results = await fakeDb.users.create({ name, email, avatarUrl })
  
  if (result.success) {
    return { errors: result.errors }
  }
  
  return result.data
}
