Query with more than 30 columns

when i create a query with a “Custom Column”, metabase creates a query like

SELECT source.id AS id,

FROM (SELECT analytics.tablename.id, …) source

When I use more than 30 columns I get an error -
ClickHouse exception, code: 47, host: 194.182.175.90, port: 8123; Code: 47, e.displayText() = DB::Exception: Missing columns:

Only for the first 30 columns the alias “source” is used

SELECT source.id AS id,

analytics.tablename.column1 AS column1
FROM (SELECT analytics.tablename.id,

analytics.tablename.column1
.) source

I don’t know if it is a problem with the clickhouse driver or a general problem

I found out it is a problem with the clickhouse driver
