target_frame does not exist

[ZhoZhicheng]

Hi, thanks for your great work. But I encounter a question. When I run elevation_mapping_cupy with turtlebot3, there is a error:
"odom" passed to lookuptransform argument target_frame does not exist.
and when i want to change the world frame in rviz, rviz died and say:
OGRE EXCEPTION(2:InvalidParametersException): Cannot destroy a null MovableObject.
But last year I use elevation_map_cupy without sensor_processing I didn't find this question. Do you know why?

This looks like a problem with the tf tree.
Can you make sure that there's a tf between odom and the sensor frame connected?

You are right, there's no 'odom' frame, also no right_wheel_link and left_wheel_link. But why this happend? Turtlebot model has some questions? Or should I add a localization program?

Okay. Sorry, then it's a Turtlebot issue rather than the elevation mapping issue. Could you please check how to publish turtle bot tf? Thanks!

Hi @ZhoZhicheng, I have the same problem and my tf tree looks the same. Did you ever figure out what the issue was?

It's a Turtlebot issue, and it's easy to solve. But I can not remember the details.

@ZhoZhicheng, I'm glad that it was easy for you to solve, but I've been trying to solve it for several days, so it hasn't been "easy" for me. Thanks anyway!
