Responses are not displayed in network tab

Used both Edge and Firefox for my project with Mercure.

Having the same problem, is there any solution ?

EventSource does not support custom headers. event-source-polyfill is implemented with fetch/XMR. It can support custom headers, but the browser tab cannot be displayed correctly.

At present, we can only accept this imperfection.

• Event does not show up in the Chrome EventStream subtab inside the Network tab when viewing the eventstream connection
• Setting headers for EventSource
