## Which issue does this PR close? - Closes #25082. ## Rationale for this change `get_field` has two map lookup paths: * `process_map_with_nested_key` uses a comparator and works for all key types * `process_map_array` uses the `eq` kernel, and therefore does not support map keys that are nested types (e.g., lists). The previous implementation arranged to call `process_map_with_nested_key` for map-typed keys, but that was too narrow: this path should be taken for list- and struct-typed keys as well. ## What changes are included in this PR? * Route every nested key type through `process_map_with_nested_key` * Add unit test and SLTs ## What is the testing strategy for this PR? Existing tests pass; new test cases added. ## Are there any user-facing changes? No, aside from addressing the bug. -- This is an automated message from the Apache Git Service.
