ORES extension failing to parse scoring response
Closed, ResolvedPublicPRODUCTION ERROR

Description

Notice: Undefined index: enwiki in /srv/mediawiki/php-1.31.0-wmf.5/extensions/ORES/includes/Cache.php on line 52
Warning: Invalid argument supplied for foreach() in /srv/mediawiki/php-1.31.0-wmf.5/extensions/ORES/includes/Cache.php on line 56

My first guess is that we're requesting from the ORES v1 endpoint, and trying to parse it as a v3 response. @Ladsgroup may have already patched this?

Event Timeline

I have a feeling that the patch is not deployed yet.

My guess must have been wrong. Your patches for T178962 are deployed, and we should no longer be hitting the v1 API from the extension. Now I'm thinking these might be error responses?

This is really really spammy in production, raising to UBN!
