    Hi,

    We've managed to resolve the issue, and it appears to be related to a bug. The problem arose after a new release of the Gateway we were using to read files into the bronze stage. Initially, we had already transformed data to bronze using the older version of the Gateway. However, once the new release was applied, the issue emerged during the transformation process from bronze to silver.

    Despite updating the Gateway to the latest version, the issue persisted. To resolve it, we had to delete all the existing tables/files and reload the data into bronze, followed by a transformation to silver using the updated Gateway.

    This seems to suggest a compatibility issue between the older and newer Gateway versions during the transformation process.

    Regards,
