I'm trying to make a crone tree using ngx-graph, and link each node to a pop-up so i went for the "@material-extended/mde", the issue i have is that i'm trying to define the pop-up content by node, so i tried using the property "data". But, whenever i add any new property to the nodes (other than id and label), the parse fails and all nodes turn black.

Is there any way i can make the pop-up content work, i'm planning to have forms and data grids into the pop-up depending on the node?

Here is a link to the stackblitz i'm working on

It always fails on the node with the additional field, so i thought it should be a parse issue, or node structure is predefined and cannot have the graph with more than the 2 fields (id and label).
