UI5 serverless Internal error destination protected

[#1]

I'm migrating a UI5 app to serverless. When this runs as an application the destinations protected by xsuaa are accessed normally. But as an HTML5 app it doesn't run.

In the example application I have two destinations, one protected and one not. In the protected I have error 500.
