Jdlrobson triaged this task as Unbreak Now! priority.

Huge spike in error logs starting today. Cannot find any reference to this variable in code or gadgets and given amount of projects impacted feels like a global banner campaign. Nothing displays.

This was due to the banner CommunityWishlistVote_Mobile. Fixed with this change. Pinging @Trizek-WMF FYI

Also @Seddon: What's the best tag for non-fundraising CentralNotice banner issues?

No more logstash errors since the fix, closing this.

@Pcoombe thanks for the fix!

is there a way we can change the banner process for deploying banners to make sure logstash is checked for new errors?

I'm also happy to jump in and fix some errors if you have time to get me up to speed on how and help me get the relevant permissions.
