    subgraph site
        subgraph server
            db-PSQL-[(PostgreSQL)]
            app-NFS[/NFS Share/]
            app-Samba[/"Samba - This will break"/]
            app-OLDAP[/OpenLDAP/]
            app-SSH[/SSH/]
        end
    end

    %%This causes the exception
    click app-Samba "https://example.com"

    subgraph oldDC?
        app-oldDC[/Old SAMBA/]
    end
    
    app-OLDAP --> app-oldDC
Loading
  1. Create a config file with the elk renderer enabled
{
    "theme": "dark",
    "flowchart": {
        "defaultRenderer": "elk",
        "htmlLabels": true
    }
}
  1. Render it: mmdc --configFile "config.json" -i "input.mmd" -o "output.png"

--> Exception:

    at render (C:\Users\REDACTED\AppData\Roaming\npm\node_modules\@mermaid-js\mermaid-cli\node_modules\mermaid\dist\mermaid.js:54828:30)

The issue points to the following section in the mermaid package.

I believe that renderOptions.config is not being set, and causes the code to fail.

Desktop:

  • OS: Windows 10 Pro 22H2
  • Program Version: 11.4.0

Additional context
I tried setting securityLevel int eh config, but that didn't work, but worth looking into again.
