----------------------------------------------

The issue is a duplicate of [CALCITE-2464|https://issues.apache.org/jira/browse/CALCITE-2464]. I suggest closing this issue and continuing the discussion on the existing issue.

> The struct type (or RelRecordType) is hard coded NOT nullable, which lead exception thrown when invoking:
> {{RexBuilder.makeLiteral(null, structType);}}
> The exception looks like following:
> java.lang.IllegalArgumentException
>         at com.google.common.base.Preconditions.checkArgument(Preconditions.java:108)
>         at org.apache.calcite.rex.RexLiteral.<init>(RexLiteral.java:217)
