    end
    
    app-OLDAP --> app-oldDC
Loading
  1. Create a config file with the elk renderer enabled
{
    "theme": "dark",
    "flowchart": {
        "defaultRenderer": "elk",
        "htmlLabels": true

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.
