Report schedules are not sending attachments in mails

Problem

• On Monday 22.07.2024 at 3:52 UTC, the system began sending emails for scheduled report exports without attachments. As a result, the recipients did not receive their periodic report exports.

Action

• The engineering team promptly identified the source of the issue, resolved it, and deployed a new version of the application.
• The engineering team also identified the affected emails that were sent to recipients without attachments and resent those with a weekly or longer periodicity.

Causes

• A bug in the code responsible for creating export emails was introduced by earlier changes.

Solutions

• Enhance test coverage to automatically identify similar issues in the future.
• Refactor outdated code to ensure safer modifications.
