> I agree with @nevi-me : Array::data_type(&a) == DataType::Null if and only if a.as_ref().downcast_ref() is infalible. Good call @jorgecarleitao -- I didn't realize that the real bug was `NullArray` created by `NullArray::new_with_type` claiming to be `DataType::Int32`, etc. Since this has been fixed by @nevi-me in https://github.com/apache/arrow/pull/9469 I am feeling much better and have updated this PR's description to remove the "Note" section ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
