Hi Experts,

I have a standalone App to be embedded in FA by using page integration.

I am using the embedded database (BO).

In the landing page there should be some data from BO does not show up. means cannot read from the BO.

On the landing page when I navigate to it : I get the below errors : image 1,2, and 3.

When I try to navigate through the App, I get warning errors: Exception during RestAction: image 4 and 5

Sometimes I get the failing of GET BO.
