safari eventsource with close

When using EventSource (https://developer.mozilla.org/en-US/docs/Web/API/EventSource) library in Safari 13, with closing the connection when done,
Ex: 
var source = new window.EventSource("someurl");
source.onmessage = function(event) {
    source.close();
};


I am getting error in WebInspector inspite the status code is 200. Means behaviour is as intended, only showing error in WebInspector UI.
I have explained in image the same.

When we are not closing the EventSource object it works fine
#source.close() 

Can we solve this ?
