Preview thumbnail images fail/not generated for Site Studio Components

I have the same issue and I manage to solve it by changing one line of code in "src/Plugin/media/Source/Asset.php" - line 283.

return $this->getRemoteThumbnailUri($external_id) ?: $asset['thumbnails']['600px']['url'];

to

return $asset['thumbnails']['600px']['url'] ?: $this->getRemoteThumbnailUri($external_id);

For me $asset['thumbnails']['600px']['url'] - has right preview path and $this->getRemoteThumbnailUri($external_id); generates wrong one.

I was not digging further into it, but I hope it will help someone to fix the source of issue.

Added a patch to enforce widget_table view mode as a quick fix to this missing thumbnails issue in a default D10 site.

Hello @ibullock, Could you please outline the exact steps to reproduce the issue?

Solution: Please follow the steps outlined below:

1. Navigate to /admin/structure/media/manage/acquia_dam_image_asset/display/media_library.
2. Replace the existing field with the “Asset Reference field.” and set image style along with.
3. Finally, click “Save.”

The v2 structure format is causing issues with thumbnail generation. Therefore, we have decided to serve the thumbnail using v3 as a uniform solution.

Requesting review.

While a cursory look at the code looks ok, it'd be good to get validation here that the issue found with site studio is fixed.

Received validation that it works in Site Studio, fixed!
