How to use tf_remap??

Hello, I have a rosbag in which a /tf topic is recorded. I need to remap all tf frames in that bag which refer to the frame named '/world' to refer to a new frame named '/vision'. I tried the following but it is unfortunately not working: rosrun tf tf_remap _mappings:='[{old: /world, new: /vision}]' Am I missing something? **EDIT**: I have also tried to do it from a launch file: - {old: "/world", new: "/vision"} but it's not working :( Could it be that I am missing some argument when calling rosbag play? **EDIT 2**: After searching, I found people saying that, in addition to running the tf_remap node, rosbag should be run as follows: rosbag play x.bag /tf:=/tf_old I tried it, and still it's not working :( The tf_frames are still referring to /world rather than /vision. Any help would be highly appreciated!!
