Project Web App OData not showing Predecessor or Successors

I am able to access the dataset in the Project Web App (PWA) and pull it into Power Bi using an OData connection without issue.  However I do not see the predessor or successors in the dataset anywhere nor so i see fields such as the amount of Lag time, Total Float, or Contstraint type on Tasks, Task releationshop types.  I am trying to create reports in MS Power Bi that show the following.  

Ignore the reference to Primavera.  I am using 2019 MS Project Professional.
