Index.json is missing some resolutions

[gamebeaker]

Hello i came a cross a bug in a few releases.
Example:

Messiah

Here are the cover files on archive.org
mbid-ac286488-223f-4e8c-8f22-f33bb7c532e0 directory listing
there is an mbid-…-thumb1200.jpg

If you open the index.json file you can see that the 1200 option is missing.

Here is an example how it should look like:
Release “Loner” by Alison Wonderland - MusicBrainz
archive.org files:
mbid-ae145369-0946-4f5a-a01e-eb23286099f6 directory listing

index.json

I am not sure how this happened. I can supply more releases that have this problem if needed.
How did i came across this bug?
I set picard to download 1200 px covers and it downloaded 500 px.

Seems like this should be reported to the Cover Art Archive folks.

As this are just a few releases i found a “solution”:
My idea was that if i can get cover archive to recreate index.json the values will be correct. I can get it to recreate index.json with an edit. Here are two edits the first one removes the designation “front” and the second adds the designation “front” again reverting the first change.

Before the edits index.json looked like this:

after the two edits is looks like this:

Yes, that works, but I’d prefer people didn’t create noise like this in the edit history & peoples’ edit subscriptions. We can reindex these for you without creating pointless edits. Just contact the MusicBrainz support@ email, or drop a message in the #metabrainz room on IRC/Matrix. These files are managed by us, so don’t contact the Internet Archive.
