video_tool.py problems with rendering on an HPC

[hash-ir]

Hi,

I am running a viewer locally on an HPC cluster and using the video tool to create a script. The script is created successfully however when I try to render with a web driver, I get the following error:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: Chrome failed to start: exited normally.
(session not created: DevToolsActivePort file doesn't exist)
(The process started from chrome location /u/hashirah/.cache/selenium/chrome/linux64/125.0.6422.141/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

I tried rendering without a web-driver but it also has issues where 0 chunks are identified and the window is an empty neuroglancer viewer:

Open the following URLs to begin rendering

Here is the script which was created using the tool:

I was also wondering why the script had URLs with the prefix neuroglancer-demo.appspot.com when I launch the viewer locally and it should be localhost:1337?
