xs-app.json rewrite not working

Hello,

I'm deploying an HTML5 app from BAStudio to SCP's Fiori Launchpad using SAP Router (from the wizard, option "Managed by SAP Router") and I'm trying to rewrite a url to a subaccount destination, but it's not working.

My xs-app.json routes are defined like this:

"routes": [
    {
        "source": "^/sap/opu/odata/sap/GBAPP_PRAPPROVAL;mo/(.*)$",
        "target": "/gw/odata/SAP/GBAPP_POAPPROVAL_QAS;v=1/$1",
        "destination": "SCI_SERVICES"
    },
    {
      "source": "^(.*)$",
      "target": "$1",
      "service": "html5-apps-repo-rt",
      "authenticationType": "xsuaa"
    }
  ]

When I open the app in Fiori, the browser console shows the following messages:

And the application shows the following message:

The app is the standard purchase order approval application.

Thanks!
