Root Cause Analysis

The incident was traced to a bug within a newly released logging extension, which was intended to enhance monitoring capabilities in our authentication stack. This bug failed to validate certain properties during the login attempt, resulting in exceptions in the subsequent code.

Preventative Measures

The automated test suite will be extended to cover logging extension runtime issues on the application framework level.
