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.
