media regenerate not working

[KingMatrix1989]

Hi. it seems there is a problem in regenerate command.
I run below command:
wp media regenerate --image_size=thumbnail_60x60 23005
and it says:

BUT:
there is not any new generated image with name tomahawk-60x60 .

Hey @skmohammadi ,

Were you able to track this one down? It looks like the message says "no thumbnail regeneration needed", which would imply WP-CLI determined it wasn't necessary to regenerate the thumbnail.

wp media regenerate 616671 --image_size=thumbnail

Found 1 image to regenerate.
1/1 No "thumbnail" thumbnail regeneration needed for "693203523a89a121ed5511be" (ID 616671).
Success: Regenerated 1 of 1 images.

Is it because the metadata is missing the sizes definition? How do I add it? @danielbachhuber

Is it because the metadata is missing the sizes definition?

I don't think so. Regeneration should work even if that is missing. But hard to say without full context. I suggest asking for help in our #cli Slack channel.
