Azure function + Custom Connector + Data Table + Display View

Hello Everyone,


I have the following scenario. 


1. Azure Functions returning a list of objects in JSON format. I tested it with swagger and Postman and it works fine.

2. Data Custom Connector (+ Connection). Which works inside the "Test" tab and I get expected results but if I test in with swagger I get the error 

TypeError: Failed to fetch. 

But I think this is not my problem.

3. I'm able to get data for the DataTable with: Signals.GetAllSignals().signals  

4. I would like to show the selected item from the DataTable in a Display View and this is where I'm stuck. I use the same Data Source as for DataTable ( Signals.GetAllSignals().signals ) and for "Item" I use DataTable1.Selected. Unfortunately with this I cant select any fields and I looks like that no data is connected. Interestingly I able to use the "Vertical Gallery" but not the "Blank Gallery" with my connected Azure function.  


Any advise how I can achieve my goal?


Thank you
