PageErrorHandler doesnt redirect to mentioned path if microfrontend fails with "X-frame-options:sameorigin" error

[mayankgupta0510]

Hi,
I wanted to redirect to specific page if microfrontend fails with any error (but specifically I am looking for X-Frame-options error).
so in my example : if I navigate to "/extension" then it should load the microfrontend and ifmicrofront has X-frame-options : sameorigin then it should redirect to my specified path i.e.
"/extension.html" page
let me know if I have missed anything here.

below is my Luigi-config :

Luigi.setConfig({
navigation: {
contextSwitcher : {
defaultLabel: 'Select Subdomain',
parentNodePath: '/extension', // absolute path
lazyloadOptions: true, // load options on click instead on page load
options: () =>
[...Array(2).keys()]
.filter(n => n !== 0)
.map(n => ({
label: 'i077549-dev', // (i.e mapping between what the user sees and what is taken to replace the dynamic part for the dynamic node)
pathValue: '?~subdomain=i077549-dev' // will be used to replace dynamic part
}))
},

    nodes: [{
        pathSegment: 'home',
        hideFromNav: true,
        hideSideNav: true,
        viewUrl: '/newhome.html',
        loadingIndicator: {
        enabled: false,
        pageErrorHandler: {
            timeout: 3,
            errorFn: () => _utils.setWindowLocationHref('extension')
        }
      }
    },{
      pathSegment: 'extension',
      hideFromNav: true, 
      hideSideNav: true,
      loadingIndicator: {
        enabled: false
      },
    onNodeActivation : function(){
        console.log("Node Activated");
    },
      pageErrorHandler: {
            timeout: 3,
            redirectPath: '/extension.html#subdomain={nodeParams.subdomain}'
      },
      viewUrl: 'https://sap-cloud-platform-home-i077549-dev-development-saptest.cfapps.sap.hana.ondemand.com/'
    }],
  appSwitcher :{
    showMainAppEntry: true,
    items: [
      {
        title: 'Extension suite',
        link: '/extension'
      },
    ]
  }
        
},
routing: {
    useHashRouting: false,
    nodeParamPrefix: '~'
},
settings: {
    responsiveNavigation: 'Fiori3',
    header: {
        title: 'SAP Cloud Platform Home'
    },
    customSandboxRules: ['allow-top-navigation'],
    iframeCreationInterceptor: (iframe, viewGroup, navigationNode, microFrontendType) => {
        if (microFrontendType !== 'modal')
            iframe.allowFullscreen = true;
        }
}

I have an microfrontend : "https://sap-cloud-platform-home-i077549-dev-development-saptest.cfapps.sap.hana.ondemand.com/’"

We should add to the documentation that the PageErrorHandler works only if loading indicator is not disabled.
