4. postmortem Oct 28, 2025, 07:40 PM UTC

   **Impact** At least one user experienced issues when attempting to generate fixes. The issue started on UTC-5 25-10-21 14:31 and was proactively discovered 3.1 days \(TTD\) later by a staff member who reported through our help desk [\[1\]](https://help.fluidattacks.com/agent/fluid4ttacks/fluid-attacks/tickets/details/944043000051528937) that both Auto Fix and Custom Fix were not working, either from the platform or the IDE extensions. The problem was resolved in 3.1 days \(TTF\), resulting in a total window of exposure of 6.2 days \(WOE\) [\[2\]](https://gitlab.com/fluidattacks/universe/-/issues/18525). **Cause** While updating the internal logic of our Fixes module, a new version of a library responsible for handling connections with AWS services was introduced. This update caused an incompatibility that led to an error preventing the execution of Fixes-related processes. As a result, both the Custom Fix and Suggested Fix features stopped working across the platform and IDE integrations [\[3\]](https://gitlab.com/fluidattacks/universe/-/merge_requests/86964). **Solution** The change that caused the incompatibility was reverted, restoring the previous version of the library to recover normal operation of the Fixes module [\[4\]](https://gitlab.com/fluidattacks/universe/-/merge_requests/87454). **Conclusion** We will strengthen our test coverage to detect dependency-related incompatibilities earlier and avoid similar issues in the future. **INCOMPLETE\_PERSPECTIVE < MISSING\_TEST**
