Error launching code env for R on a system with no internet access

Hi,

I am working on a sytem with no internet access, Integrated R and DSS using: https://doc.dataiku.com/dss/latest/installation/r.html#case-2-if-your-dss-server-does-not-have-internet-access



Error while launching code-env for R:

specifying the directory path in CRAN mirror URL: file:///opt/dss/R-packages/R-packages/

This is the path on the local system where all the packages are placed.

Error message:
