How to resolve "Unhandled Promise Rejection: NotSupportedError: The operation is not supported." in Safari - Angular?

I'm getting the above error only in the Safari browser, which is not happening in my local machine to debug. I removed the minified version of the build while digging further and the error seems to be from Zone.js.

I'm unable to debug further and unsure why it is happening. It is not happening in other browsers.

It's been not easy to debug the minified version of the Zone.js library. How can I proceed further to resolve this?

I don't think there is any impact on the functionality but it keeps bothering me.

There were similar errors I found but they are related to Audio/Video files. Still, in my case, the error is happening on every page wherever I navigate and only happens for the first load of any page. I also don't get any errors/failures from API calls.
