what release version of ROS 2 are you using? did you build the bridge yourself or are you using pre-built binaries? the bridge error messages you see suggest you're either using an outdated version of `ros1_bridge` or that you have custom-built the `ros1_bridge` yourself and are missing support for TF2 messages. --- [Visit Topic](https://discourse.ros.org/t/cartographer-and-navigation-workable-in-beta2/2074/6) or reply to this email to respond.
