If you read the error then it is quite obvious what is the error... It is not the error with the binaries, you just gave wrong value type in the launch file

I read the error and I don't understand it, I didn't change any valor in the launch file. Can you be more explicit in any way, or give any solution? Thanks

Please use ros2 branch, there is a commit here that should fix that problem (https://github.com/introlab/rtabmap_ros/issues/725).
