# [DRILL-8512](https://issues.apache.org/jira/browse/DRILL-XXXX): ReduceAndSimplifyFilterRule fails with NullPointerException ## Description I'm not sure why the following issue wasn't before, but it's clear, why the issue appears at all - because we provide neither inputs `RelNode`s(we calling `DrillOptiq.toDrill` with `null` for the input, see code change) or `RexBuilder` along with `RelDataType`. ## Documentation - ## Testing Tested with the query the issue was reproduced: ```sql SELECT * FROM ( SELECT (CASE WHEN (true) THEN 'qwe' ELSE null END) res1 FROM (VALUES(1)) test_tbl ) test where res1 IN ('ab','dab','qw','qwe') ``` -- This is an automated message from the Apache Git Service.
