Editors are invited to check any graphs they have recently edited for such errors and also review the list of graphs with known problems below:
# Background
A large amount of graphs on deployed wikis were badly configured and were accounting for up to 50% of all JavaScript errors in Wikipedia wikis. As a result of this, we have stopped logging these errors and instead are sending a message to the browser developer console (e.g. [[ https://developers.google.com/web/tools/chrome-devtools/open | Chrome dev tools ]]). (see T274557)
