Description

When you pass a Scalar and a ChunkedArray with 2+ chunks to the or_kleene or and_kleene kernel, it returns all null in the result.

Demonstrating this with the R bindings:

> call_function("or_kleene", Scalar$create(TRUE), ChunkedArray$create(c(T,F,T), c(F,T,F)))
ChunkedArray
[
  [
    null,
    null,
    null,
    null,
    null,
    null
  ]
]

Compare to the following which all work as one would expect:

Scalar and ChunkedArray with only one chunk (works as expected):

> call_function("or_kleene", Scalar$create(TRUE), ChunkedArray$create(c(T,F,T)))
ChunkedArray
[
  [
    true,
    true,
    true
  ]
]

Scalar and Array (works as expected):

> call_function("or_kleene", Scalar$create(TRUE), Array$create(c(T,F,T)))
Array
<bool>
[
  true,
  true,
  true
]

Two ChunkedArrays (works as expected):

> call_function("or_kleene", ChunkedArray$create(c(T,NA,T), c(F,F,T)), ChunkedArray$create(c(T,NA,T), c(F,F,T)))
ChunkedArray
[
  [
    true,
    null,
    true,
    false,
    false,
    true
  ]
]
