I am trying to create an app based on a rest API. Got most things working an I understand, thanks to @v-xida-msft , what I can and can't do with the REST Api.
So I am using collections to store some data, but one of the collection won't show the nested objects. I updated the connector and the response part, it shows the nested fields and also the test of the custom connector is showing the correct results.
But in the app I don't get nested data in the collection, and I can't find the reason why.
