Please have a look into the code we are shifting to the Bryntum Gantt, previously we have DHTMLX Gantt implemented. We are having Object Variable in which activity/ projects data is coming and then we were using that object to make a Gantt Chart.
I have talked with Mats and get to know that we have to add datafields by using data source if our datafields differ from default datafileds to Bryntum. Please have a look into the code I think I'm not passing the data in right way please let me know of this. I'm also sharing index 0 of our object data. Gantt chart is working only if I enter static data into it or use any json file that you provied in you example code.
Zip file attached for code and object data is attached here (only index 0).
