Issue Summary

Whenever changes are made to the hook settings, the Audit logs do not show the 'old setting' for “Repository hook settings changed for repository” and “Repository hook settings changed for project” events.

This is reproducible on Data Center: (yes)

Steps to Reproduce

1. Add a test hook plugin to your Bitbucket instance repo/project.
2. Change some settings in the hook plugin.
3. Check the audit log event logged for “Repository hook settings changed for repository” or “Repository hook settings changed for project”.
   

Expected Results

Audit logs should show the 'old setting' for “Repository hook settings changed for repository” or “Repository hook settings changed for project” events.

Actual Results

The 'old setting' is missing from the Repository hook settings changed for repository Audit event that is logged. Also the JAVA Event API repositoryHookSettingsChangedEvent.getOldSettings() is empty.

Workaround

There are no workarounds for this. A workaround will be added once it is available.
