comphead opened a new issue, #16187:
URL: https://github.com/apache/datafusion/issues/16187
### Describe the bug
The query below crashes
```
> select map_values(map([named_struct('a', 1, 'b', null)],
[named_struct('a', 1, 'b', null)]))[0] as a;
thread 'main' panicked at
/Users/xxx/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/arrow-array-55.0.0/src/array/null_array.rs:149:9:
NullArray data should not contain a null buffer, as no buffers are required
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
It is expected to handle this gracefully, if index is not found it should
return NULL
