Crash with wrong topic type

[Tobias-Fischer]

I get the following error: [ERROR] [1597284029.114291]: [Client 0] [id: subscribe:/tf:6] subscribe: Tried to register topic /tf with type tf2_msgs/TFMessage but it is already established with type tf/tfMessage and jupyter-lab subsequently crashes.

Related: where can I find the config files to remove the tf topic for now?

Related to the error, I need more information to dig into.

To start rosmaster, the extension launches a launch file with:

<launch>
  <node name="rosapi" pkg="rosapi" type="rosapi_node" />
  <node pkg="tf2_web_republisher" type="tf2_web_republisher" name="tf2_web_republisher" />
</launch>

From settings, you can change this file adding the path to your own, but you need to keep the rosapi node otherwise Zethus won't work. In addition, if you don't runtf2_web_republisher Zethus will complain getting the following error:
