Launch turtlebot_bringup.launch.py not working

[DJ1NN1]

So I have tried to ros2 launch turtlebot2_bringup turtlebot_bringup.launch.py after building the kobuki base from source, but for some reason I get the following Error:

• [INFO] [launch]: All log files can be found below /home/autlab3/.ros/log
• [INFO] [launch]: Default logging verbosity is set to INFO
• [ERROR] [launch]: Caught exception in launch (see debug for traceback): Node.init() missing 1 required keyword-only argument: 'executable'
