Getting unknown exception while using Telerik Media Query with Safari browser

While using Safari browser, I am getting following exception message:

 

SyntaxError: Unexpected private name #a. Cannot parse class method with private name.

Hello everyone,

@Jack - the mot common reasons for "TelerikBlazor was undefined" are documented and I assume that your case is related to the possible race condition (defer / autostart), otherwise the error will appear consistently.

@Kasim - the original problem here seems this one, so I will close this public item.

Regards,

This likely isn't a browser or OS specific issue. I am experiencing basically the same thing from time to time, in Windows 10 using Google Chrome browser.

If I create a sample application, it works for a while. Then I change something in the application and start it up and it crashes. In my case, I get:

Unhandled exception rendering component: Could not find 'TelerikBlazor.initMediaQuery' ('TelerikBlazor' was undefined).
at http://localhost:5130/_framework/blazor.server.js:1:497
at Array.forEach (<anonymous>)
...

The page indicates it failed and offers to reload. If I reload, then it works again.

So there is either some kind of race condition going on in Telerik's javascript code, or who knows. This needs to be looked into and corrected. It is not reproduceable every time. Static analysis of the javascript needs to be done and figure out why it would sometimes do this.

Hello Kasim,

I navigated the site with a MacBook Pro 2021 with the latest Safari and macOS version. I can report that I did not get any issues in the console. Can you send me a runnable reproduction so that we can further investigate?

Hello Kasim,

I would like to ask for a runnable code snippet where we can reproduce the behavior. I navigated to this website on an iPhone 13 Pro Max and got no exception. You can see our Isolating a problem in a sample application blog post for some more information on creating reproduction snippets.

Hello Kasim,

I have tested the MediaQuery in the latest Safari browser (with the sample snippet from the Overview documentation article, and the online demo) and I was not able to reproduce the error you reported to us. Based on that, I would like to ask for a runnable code snippet where we can reproduce the issue and investigate it.
