OK so what’s the problem? Just ignore those malformed images and carry on.

(Or edit them out of they posts they are probably in?)

These are not malformed images, they display correctly in the post.

What is malformed (or rather not generated) is the ‘quick scroll’ optimised image, which fails to generate from the original.

It can be detected as missing when quick scrolling through the post.

I have edited the title for clarity.

Hi, @md-misko
Did you happen to solve your problem?
I happen to face similar issues.

I have since migrated to S3 and cannot run rake uploads:missing anymore against the S3, but I’ve checked the one file referenced above and it has a non 0 size on S3 now, so it seems this was fixed.

Are you on latest build?

Oh! I didn’t know that this command isn’t meant for S3 buckets.

Yes. I always keep upgrading to the latest. At the most, I may be behind 2-3 days sometimes.

In any case, if you might happen to know, what’s the best command to find the missing uploaded images, or what is the command to map the posts urls to correct images in the correct basket (if for some reason the paths got corrupt)?

This seems unrelated to the issue described in the OP, perhaps open a new topic in support and describe exactly what your problem is.
