Cloudfront distribution 404 after update

What are the steps to reproduce this bug?

1. uploaded png / gif assets
2. updated webiny (env prod) 5.38.2 -> 5.39.6 according update document
3. trying to fetch any asset.

What is the expected behavior?

Assets should remain usable.

What do you see instead?

Assets are not found by Cloudfront: 404. The S3 bucket seems still filled, a random choice of assets shows that they are available there.

Additional information

I had a partly broken Webiny instance for some time due to the Node 16 Lambda runtime deprecation.

Possible solution

I traced the issue down to the lambda which cannot resolve the metadata file. I can confirm, that the *.metadata file does not exist for us for assets which have been uploaded with the 5.38.2 webiny version but for uploads with the updated version.

1. Should this file exist for 5.38 uploads?
2. How can we hotfix this? Is there any way to recreate them? Are these files AWS or Webiny specific?
