bc_vt_codeserver app fails to launch on DGX nodes due to missing modules

[matthewabrown]

When a user launches Codeserver IDE app on DGX nodes (probably A100 nodes have same issue), they get a page with:

"Not Found

The requested URL was not found on this server."

The output.log for the session shows the issue is missing software modules on that node type.

Lmod has detected the following error: The following module(s) are unknown:
"app_code_server" "project/ondemand"

Please check the spelling or version number. Also try "module spider ..."
It is also possible your cache file is out-of-date; it may help to try:
  $ module --ignore-cache load "app_code_server" "project/ondemand"

Also make sure that all modulefiles written in TCL start with the string
