We are effected by this issue - just raised here too for visibility.

New Packages for Jazzy Jalisco 2026-04-13

Unfortunately, ros-jazzy-rosidl-generator-rs version 0.4.11-1 contains a bug that raises a TransientParseError when building message definitions in our setup. This issue has already been fixed upstream (https://github.com/ros2-rust/rosidl_rust/pull/20), but the fix is only available starting from version 0.4.12, which is not included in this sync.
