Unexpected token error when running rosbridge with rclnodejs 0.18.0
See original GitHub issueSince the upgrade of rclnodejs from 0.17.0 to 0.18.0 running the rosbridge (ros2-web-bridge) fails with
# node /node_modules/ros2-web-bridge/bin/rosbridge.js
/external/rclnodejs/lib/context.js:47
static _instances = [];

The environment is pretty standard, I guess:
- docker image ros:foxy-ros-base
- ROS 2 Foxy
- Ubuntu 20.04.1 Focal
-
$ git submodule status +b082bb74a75c1773d70b2e00850468779374cd00 external/rclnodejs (0.18.0) +248f2ee44c525ebbd7c90e7c056ba62f3939eb02 external/ros2-web-bridge (0.3.0) -
# node --version v10.23.1
We build rclnodejs and ros2-web-bridge from source in a Dockerfile with the commands
# install Nodejs
RUN curl -sL https://deb.nodesource.com/setup_10.x | bash - && apt-get -y install nodejs
COPY external/ros2-web-bridge /external/ros2-web-bridge
COPY external/rclnodejs /external/rclnodejs
RUN /bin/bash -c ". /opt/ros/$ROS_DISTRO/setup.bash && npm i /external/rclnodejs && npm i /external/ros2-web-bridge"
Any idea what could be wrong? When checking out version 0.17.0 in submodule rclnodejs, it works (but with the issue in #752).
