websocket connection error in Paraview web osmesa docker image

Hi,

I am trying to run Paraview web Visualizer inside docker. For this, I used osmesa-visualizer docker image using the command:

docker pull kitware/paraviewweb:pvw-visualizer-osmesa-master

But when I run the docker, it runs the apache server and also launcher. When I go to web browser using the link http://localhost:9000/visualizer, I get the following error presented in the image below:

The logs in the laucherLog.Log is captured and also proxy is popped with unique no.
What work around needs to be done?

Regards,
Sunag R A.
