Problem with all examples in ros3djs repo on localhost

[martin-pc]

I am currently running Ubuntu 18.04 and ROS melodic. Currently, I am not able to get any of the examples using chrome or fixefox. Below are the steps I follow

1. I checkout the ros3Djs repo
2. follow the guide for setup and building.
3. Then I start the rosbridge_websocket
4. In chrome or firefox i load interactivemarkers.html Below are the error I get from the rosbridge_websocket:

Chrome creates the 'file://' and Firefox the 'null' response. I am currently missing something here, but I do not know what.

Exact same problem with ros2djs.

You need to either enable local file loading in Chrome or run a web server to host/serve the files on the robot

This is potentially due to a bug in rosbridge preventing local file origins from working. Should be fixed by https://github.com/RobotWebTools/rosbridge_suite/pull/469 which will be in the next rosbridge release.
