'str' object has no attribute 'format__map' when build package with colcon

[yugushihuang]

I have followed the instruction https://www.lgsvlsimulator.com/docs/create-ros2-ad-stack/

And try to build the package using colcon as it states in the tutorial.

source /opt/ros/crystal/setup.bash cd ~/ros2_ws colcon build --symlink-install

but my package build failed with error 'str' object has no attribute 'format__map'

Could you please help me look into this?

I'm sorry for the late response, but I'm not able to reproduce your issue. Please make sure you are building your ros packages inside the provided docker container.

By the way, the instruction describes how to create your own ROS2-based AD stack in general along with LGSVL Simulator. For this particular repo, you might want to look at this documentation instead and you can simply run docker-compose up build to build ROS2 packages.
