External error: query failed: DataFusion error: Internal error: UDF returned a different number of rows than expected. Expected: 7, Got: 6.
This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker
[SQL] select array_has(column1, make_array(5, 6)),
       array_has(column1, make_array(7, NULL)),
       array_has(column2, 5.5),
       array_has(column3, 'o')
from arrays;
at test_files/array.slt:5161

The omitted row is where column1 = null
