Errored Elements in Workbooks

Incident Report for Sigma Computing

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.
