Segementation Fault #159

Closed eden-desta closed 3 years ago

eden-desta commented 3 years ago

Hi Folks!

I am getting a segmentation fault with the webbridge. It happens rather randomly I'm not quite sure how to go about tracking its problem. For your reference, all I am currently doing is subscribing to my joystick data that I am publishing via a Joy node (this is separate and running ROS2 foxy). 

Websocket started on ws://localhost:9090

Please require the top-level module when using the Node.js CommonJS module or use ECMAScript Modules when bundling for the browser. See https://github.com/uuidjs/uuid#deep-requires-now-deprecated for more information.
Segmentation fault (core dumped)

Is there something I am missing? Any help would be great! Thank you! And also -- it runs for a while prior to crashing.

If you are using Node.js v12.19.0, I suspect there is an issue which may cause the segfault and has been fixed. So please try v12.18.4 or wait for the next release (v12.19.1?). Also, this problem is tracked https://github.com/RobotWebTools/rclnodejs/issues/713 on rclnodejs.
