The following query is throwing a "param not found" in calcite whereas the same

select *
from (select array(1, 2, 3) as arr) as t1 inner join
(select 1 as v) as t2 on "EXISTS"(arr, x -> x = t2.v); {code}
The following error reported for the above query is
{code:java}
> java.sql.SQLException: Error while executing SQL "select *
> from (select array(1, 2, 3) as arr) as t1 inner join
> (select 1 as v) as t2 on "EXISTS"(arr, x -> x = t2.v)": From line 3,
> column 54 to line 3, column 57: Param 'T2.V' not found in lambda expression
> '`X` -> `X` = `T2`.`V`' {code}
Steps to repro:
