Hi all, It seems like there's a bug in MakeArrayFromScalar for FixedSizedBinaryType. https://github.com/apache/arrow/blob/e990d177b1f1dec962315487682f613d46be573c/cpp/src/arrow/array/util.cc#L516
```c++ template <typename T> enable_if_t<is_number_type<T>::value || is_fixed_size_binary_type<T>::value || is_temporal_type<T>::value, Status> Visit(const T&) { auto value = checked_cast<const typename TypeTraits<T>::ScalarType&>(scalar_).value; return FinishFixedWidth(&value, sizeof(value)); } ``` ` sizeof(value)` doesn't give the byte width of FSB type, does it? -- Niranda Perera https://niranda.dev/ @n1r44 <https://twitter.com/N1R44>
