Sigma Computing: Errored Elements in Workbooks
Timeline of updates
- resolved
On December 17, some Sigma users encountered column errors—such as "Reference to errored column" and "Expression contains errors"—when loading visualizations and tables. This issue surfaced as a result of introducing a workbook performance enhancement to the product.
The issue has been resolved by reverting the recent change, and the Sigma application is now fully operational. We will conduct a thorough root cause analysis and share a detailed postmortem in the Sigma Community in the coming days.
