No data in SAP BUILD Preview

Question

I am working on a SAP Build Apps project. I'm trying to consume some data from the BTP via destination in SAP Build Apps.

So far I managed to create a destination on BTP, create a destination SAP Build, configure the authentication and successfully test the connection. I receive the data from the backend. I also bound the data to the UI in SAP Build and I can see the correct values in the SAP Build UI Canvas. However, I can't get the data to show in the preview.

So far I tried:

• Binding the value to the using the formula and assigning the value from the data variable e.g. data.Test_API1.profiles[0].attributes.lastName
• Using the Get record collection and binding the value to an app or page variable.

I also tried binding the value to the 'Output value of another node' and I get the error:

Also, what I don't understand is that I can see that when doing the GET request in the network tab the bearer token is undefined:

Authorization: "Bearer undefined"

But the response returns a success and I can see the data in the responseText:

Did anyone have a similar issue?

Thanks!
