Hello Katravath,
The addTaskLayer method is only available in the Pro and Trial versions:

1253×1049 111 KB

So, if you see that error message, it means that you didn’t install the Pro and Trial version in your project.

You can install Gantt as an NPM package the following way:

  1. Unpack Gantt to a specific folder, for example, to /opt/gantt_pro
  2. Use the following command to install Gantt:
npm install /opt/gantt_pro

You can read more about installation methods in the following article:
