Clickhouse setting config failed

I need use experimental function of ClickHouse.
For it use version 21.5.5.12
spring:
data-source:
url: jdbc:tc:clickhouse:21.5.5.12://hostname/databasename?TC_INITSCRIPT=init.sql

And init.sql contains this line:
SET allow_experimental_window_functions = 1;

on this line i have next error:
Request processing failed; nested exception is org.springframework.jdbc.UncategorizedSQLException: StatementCallback; uncategorized SQLException for SQL [SET allow_experimental_window_functions = 1]; SQL state [null]; error code [113]; ClickHouse exception, code: 113, host: localhost, port: 32811; Code: 113, e.displayText() = DB::Exception: There is no session or session context has expired (version 21.5.5.12 (official build))
; nested exception is ru.yandex.clickhouse.except.ClickHouseException: ClickHouse exception, code: 113, host: localhost, port: 32811; Code: 113, e.displayText() = DB::Exception: There is no session or session context has expired (version 21.5.5.12 (official build))

Reproduce the issue using the ClickHouse 21.5.5.12 JDBC URL and the init.sql statement shown in the report. Start by tracing how the Testcontainers JDBC URL runs init.sql and how the ClickHouse container handles session-scoped settings. Done means the experimental setting can be applied from init.sql without the session-context error.
