For some reason I can't get view the source so I don't have exact line
numbers, but IntelliJ was kind enough to decompile this part
(SqlTypeUtil.class) for me. This appears to be the exception I'm hitting.
if (!isAtomic(type) && !isNull(type)) {

It got there because isAtomic returns false for interval types:
public static boolean isAtomic(RelDataType type) {
> SqlTypeName typeName = type.getSqlTypeName();

Seems like a bug?
