You might find a reference to which file failed via Admin \> Logs \> Error Logs

If that doesn’t help, I think searching the database for posts with `cooked` that contain `yourdomain/uploads/` will get you a list of those 19 posts mentioned in the migration status. Worst case, you could then manually look at those and compare any uploads with what’s in S3.

Something like:

```plaintext
rails c
Post.where("cooked like '%discourse.example.com/uploads/%'")

```
