payload.create Media does not set width, height, and sizes

[gvocale]

I have a Node.js script that seeds a Collection and its related Media:

const createdImage = await payload.create({
  collection: "media",
  data: {
    alt: imageName,
  },
  file: {
    data: fileBuffer,
    mimetype: `image/${path.extname(imageName).substring(1)}`,
    name: imageName,
    size: fileBuffer.length,
  },
});

console.log("createdImage", createdImage);

const responsiveImage = await payload.update({
  collection: "media",
  id: createdImage.id,
  data: createdImage,
  overwriteExistingFiles: true,
});

console.log("responsiveImage", responsiveImage);

Logs:

After payload.create

createdImage {
  id: 97,
  alt: 'hero.jpg',
  updatedAt: '2025-03-06T18:20:01.194Z',
  createdAt: '2025-03-06T18:20:01.178Z',
  url: '/api/media/file/hero-18.jpg',
  thumbnailURL: null,
  filename: 'hero-18.jpg',
  mimeType: 'image/jpg',
  filesize: 4219980,
  width: null,
  height: null,
  focalX: null,
  focalY: null,
  sizes: {
    thumbnail: {
      url: null,
      width: null,
      height: null,
      mimeType: null,
      filesize: null,
      filename: null
    }
  }
}

After payload.update

responsiveImage {
  id: 97,
  alt: 'hero.jpg',
  updatedAt: '2025-03-06T18:20:01.447Z',
  createdAt: '2025-03-06T18:20:01.178Z',
  url: '/api/media/file/hero-18.jpg',
  thumbnailURL: '/api/media/file/hero-18-300x300.jpg',
  filename: 'hero-18.jpg',
  mimeType: 'image/jpeg',
  filesize: 1673021,
  width: 2500,
  height: 3333,
  focalX: null,
  focalY: null,
  sizes: {
    thumbnail: {
      url: '/api/media/file/hero-18-300x300.jpg',
      width: 300,
      height: 300,
      mimeType: 'image/jpeg',
      filesize: 26640,
      filename: 'hero-18-300x300.jpg'
    }
  }
}

Questions:
1. Why does payload.create not set width, height, and sizes?
The sizes object is null in payload.create, but it gets populated after payload.update.

2. Error: The following field is invalid: filename (Value must be unique)
I’m getting this error when running the script:

Error uploading image: ValidationError: The following field is invalid: filename
    at upsertRow 
...
[ 'Value must be unique' ]

Possible Cause:

Is this error caused by filename: null left by payload.create?
