Snowflake connectors are failing with "SQL compilation error: not enough arguments for function CONCAT_WS"

The fix has restored normal functionality to all affected connectors, and the incident is now resolved.

We have implemented a fix to address the error, and the affected connectors are beginning to sync. We will continue to monitor all affected connectors until they fully resume normal sync functionality.

We've identified a problem with the hash calculation for primary key-less tables. In our process, we use Snowflake's CONCAT_WS() function, which concatenates columns with a specified delimiter. However, we've discovered that the connectors are failing because the function expects a list of columns, but an empty list is being passed instead. This mismatch is causing the failure; we will update you as the fix is raised.

The issue has been identified and we are working to resolve it.
