Mobile app - Wappler back end - server connect not returning any data

Hi,
Wappler node.js backend and creating a mobile app (separate project).

I have the login working as it returns Identity correctly -

(thats is the user id and it changes with whichever user I log in as so assume it is working)

And then redirects to another page, so all good there (thanks @brad).

Now when I try to load some information on the new page (server connect to an API that works on the backend) I am not getting any results.
Turned on debug and I am seeing the following:

I have tried the API with and without a security provider, by using the user ID as a parameter, anything else I can look at?
It works fine in the backend loading all the data and querying it by user permission etc but not through the mobile app.
Any pointers on what I should be looking at?
Thanks, Paul
