VIP with Method not allowed 405

I am trying to use the process documented here Novartis/cellxgene-gateway#96 to pack all three components together but when I try to use VIP, I get Method not allowed 405 HTTP error.

I am not sure if you can user gateway with VIP since VIP cannot use naive cellxgene. This means you have to install cellxgene through VIP.
I am not sure the 405 error, sounds like the HTTP cannot access the python flask server started by 'cellxgene launch' command

I think I found the issue.
The VIPurl in interface.html is loaded after some piece of code that refers to D3. In my case the d3.js was blocked by firewall, and could not be loaded making VIPurl to be ''. Any POST requests to the window url were not allowed.
So, I think you should wrap all dependencies in try - catch blocks and report if they cannot be loaded but let the VIPurl to load normally or move the VIPurl assignment upper in the init method.
