Default relations are ignored in Excel and OData export

Incident Description

On April 14, 2025, between 11:51 UTC and 16:09 UTC, customers experienced issues with Excel exports in which default relations were missing from the exported data. This issue was introduced by a change made to label placeholder handling in the import-export service, as a follow-up to a previous fix related to the OData integration.

Incident Resolution

The issue was identified shortly after a customer report and was confirmed to be linked to a recent code change. The change was promptly reverted, and a fix was deployed across all regions by 16:09 UTC. The export functionality was restored, and the incident was marked as resolved after a brief monitoring period.

Root Cause Analysis

The placeholder update introduced in the import-export service unintentionally affected the export of default relations. The change was protected by a feature flag, but the behaviour with default relations didn't have enough test coverage. This allowed the issue to pass unnoticed until reported by a customer.

Preventative Measures

To prevent similar issues in the future, the following actions will be taken:

• Improve test coverage to include default relations in export scenarios.
• Conduct more thorough manual testing for critical features before deployment.
