Root Cause

RViz2 display shows transform error. The display's fixed frame does not match the TF tree, or TF data is missing.

generic

Workarounds

  1. 92% success Set Fixed Frame to a frame that exists in your TF tree 
    Set Fixed Frame to 'base_link' or 'odom' — check available frames with ros2 run tf2_tools view_frames
  2. 85% success Verify TF is being published at sufficient rate 
    ros2 topic hz /tf  # should be >= 10 Hz for smooth display
  3. 88% success Check the topic name and message type for each display 
    Click the display in RViz, verify Topic matches ros2 topic list output

Dead Ends

Common approaches that don't work:

  1. Change RViz Fixed Frame to 'map' without a map publisher running 82% fail

    If no node publishes map frame, all displays depending on it will error

  2. Ignore the error assuming it is cosmetic 78% fail

    RViz displays with transform errors render nothing or render in wrong positions
