Missing info on EventSource

What specific section or headline is this issue about?

No response

What information was incorrect, unhelpful, or incomplete?

There is absolutely no specification on what the URL should look like and what it should be returning. Cause in the examples there is an incomplete url being used and it is absolutely unclear what it should do.

By logic, it should be returning SSE messages and the eventSource should be catching them, but that's not the case at all it seems.

What did you expect to see?

How to properly see the error messages you are receiving, cause now onerror just returns an error event with absolutely no useful information
What the called url should look like and what exact formatting and messages EventSource is expecting, what it returns. Overall how the object is used, initialized and how it handles things in detail

Do you have any supporting links, references, or citations?

No response

Do you have anything more you want to share?

Ok, it's still unclear what the url parameter should look like. Can it only be a file or any endpoint that returns a SSE stream?

Because I input a good url, but the eventSource keeps failing and it's absolutely unclear why

Well, it can be any URL that you can send requests to? This is where your server is hosted at. What's the error you are getting?
