Sudden increase in 422 errors?

We’re seeing a large number of our graphs fail due to the Grafana AJAX request failing ever since the outage several hours ago. The requests for these charts are failing with a 422 Unprocessable Entity error claiming that target is a required field, when it’s in the POST request and has been working without issue.

Has anyone else been experiencing this issue as well?
