    The fix is now deployed (writer version 4.5.0). Full load configurations will self-heal automatically on the next run. Where manual intervention is needed, we will reach out to affected customers directly.

    We apologize for the inconvenience. If you have any questions, please contact our support team.

    Identified

    We identified a bug in the Snowflake writer UI that affected numeric data type length settings for configurations created or tables added between December 16, 2025 and February 12, 2026. Custom numeric type lengths were silently reset to Snowflake defaults.

    For example, a DECIMAL(18,2) would become DECIMAL(38,0), effectively losing decimal precision.

    What is NOT affected

    Data Gateway, all Snowflake extractors and transformations, and data stored in Keboola Storage are not impacted by this issue.
