Notification Component -Error loading component

Hello,

I am creating PCF signal R notification component. I am following the documentation from the below URL

https://powerapps.microsoft.com/en-us/blog/notification-control-using-powerapps-component-framework-...

 

There were 3 parts(powerapps framework-typescript, Creating function in Azure, powerapps ) in the documentation, which i have done .

But i see Error Loading Control when i use the component. Has anyone faced similar kind of problems particularly for this component or do you have any fix or advice to me. 

Please let me know if i need to share any other information.

 

Regards

Vani

The issue relates to CORS or Cross Origin Resource Sharing see https://auth0.com/blog/cors-tutorial-a-guide-to-cross-origin-resource-sharing/ 

 

Your function in Azure needs to return a Access-Control-Allow-Origin header in the response but I suspect adding just 

 

req.HttpContext.Response.Headers.Add("Access-Control-Allow-Origin", "*");

 will be enough.

Hi, Thanks for the response. Please could you let me know where should i paste the code exactly. Is it in the function which i created in Azure. if yes, that function is not editable for me.

how can i edit that ? Please could you let me know?

Thanks

 

 

Hej,

I do agree with Ben. I would also say it is because of CORS.

As I know you can configure this in your Azure portal. When you open the Function, go to the tab "Platform features" and open "CORS" under API a flyout configuration will come in from the right. There you can add your source. I would not recommend adding a "*" there because this will allow requests from everywhere.
