Is there any way to direct read the param from the community URL.

For example I have a custom page with URL like https://abc.com/s/testing?testingAttribute=abc and I want to get the passed testingAttribute attribute and pass the same to the flow added in that community page.

Using lightning:isUrlAddressable I can set the value : var pageReference = { type: 'type to do', attributes: { componentName: 'c__helloTarget', }, state: { "c__firstname": "John" } }; component.set("v.pageReference", pageReference);

and get the same in other component like `var myPageRef = cmp.get("v.pageReference");

However when i am trying to access the values directly Its not working.On the JS side I am using like this :

    init : function (component) {

        // Find the component whose aura:id is "flowId"
        var flow = component.find("flowId");
        // In that component, start your flow. Reference the flow's Unique Name.

You can use design time attributes to bind the query string parameters to your component. Define these in your component's .design file.

    <design:attribute name="myAttribute" default="{!myAttribute}" description="Automatically bind the url parameter to the component variable" />

You will need a corresponding attribute in your component's .cmp file.

<aura:component implements="forceCommunity:availableForAllPageTypes">
    <aura:attribute name="myAttribute" type="String" access="global" />


Important: You must remove and re-add your component onto the community page, then publish the site for new attributes to take effects.
