Why is my Fiori application no longer working when started from the launchpad (FPS1)?

[informatics_lis]

After upgrading to FPS1, my Fiori application is no longer working, when it is started from the launchpad. Starting it by using its full URL is working fine, but when I run it from the launchpad I get these errors:

Uncaught (in promise) TypeError: this.getRouter().initMaster is not a function

Uncaught (in promise) TypeError: this.getOwnerComponent() is undefined

 I don't get any of them on older system or when the application is hosted on the BTP.

Here is the part of the source code where the errors occur. I can post more if required:

], function (UIComponent, Device, JSONModel, /* ... */) {
"use strict";

/* ... */
return UIComponent.extend("xxx.xxx.Component", {
/* ... */
init: function () {
var mConfig = this.getMetadata().getConfig();

var oParameters = this.getComponentData().startupParameters;
var aUrlParametersForEveryRequest = ["sap-server", "sap-client", "sap-language"];

for (var parameter in oParameters) {
aUrlParametersForEveryRequest.push(parameter);
}

// Create and set the ODataModel
var oModel = models.createODataModel({
urlParametersForEveryRequest: aUrlParametersForEveryRequest,
url: this.getMetadata().getConfig().urlPrefix + this.getMetadata().getConfig().serviceUrl,
config: {
metadataUrlParams: {
"sap-documentation": "heading"
}
},
startUpParams: this.getComponentData().startupParameters
});
this.setModel(oModel);
this._createMetadataPromise(oModel);

// Set the i18n model
this.setModel(models.createResourceModel(mConfig.i18nBundle), "i18n");

// Set the device model
this.setModel(models.createDeviceModel(this.geMode()), "device");

// Set the FLP model
//this.setModel(models.createFLPModel(), "FLP");

// Initialize the error handler with the component
this._oErrorHandler = new ErrorHandler(this);

// Call the base component's init function
UIComponent.prototype.init.apply(this, arguments);

/* ... */

// Create the views based on the url/hash
models.setRouter(this.getRouter());
this.getRouter().initMaster();

What changes do I have to make, so that this application will run on FPS1 system while still being compatible to older systems?

Did you invalidated all caches after the upgrade?
