### Describe the bug, including details regarding any error messages, version, and platform. Hi there! It seems there is a regression in version 22.0.0 related to `pyarrow.flight.GeneratorStream` and this change https://github.com/apache/arrow/pull/47115 (based on the error message). When using the GeneratorStream, it now fails with ``` Unknown error: Writer should be initialized before reading Next batches ``` I created a repo with the reproducer here: https://github.com/no23reason/arrow-generator-stream-repro I am running on macOS 26.1 on M1 but I presume the bug is platform-agnostic. ### Component(s) FlightRPC, Python -- This is an automated message from the Apache Git Service.
