Description

Given a UDF func that accepts a ROW(INT, STRING) as parameter, it cannot be called like this:

SELECT func(ROW(a, b)) FROM t

while this works

SELECT func(r) FROM (SELECT ROW(a, b) FROM t)

 

The exception returned is:

org.apache.flink.table.api.ValidationException: SQL validation failed. null

with an empty UnsupportedOperationException as cause.
