I am trying to get IBM's Decision Optimization Center up and running.

I am at this step (running in elevated Ubuntu cmd on Windows 11 Pro 25H2) which all goes well until I get:

EPERM: operation not permitted, copyfile '/tmp/<folder-directory>/dot-gitignore' -> '/tmp/<folder-directory>/.gitignore'

where <folder-directory> is the project name provided, when running ./generator.sh

How can I fix this issue?

I also have Docker Desktop (v4.49.0) and Node.js (v25.0.0) installed.
