How to prevent “net::ERR_SPDY_PROTOCOL_ERROR 200” when connecting an Event Source to a Java Function that...
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am using an EventSource in Javascript to connect to a Java Spring Boot endpoint.
This works fine when I connect the app to my localhost java server but while connecting to my dev server I keep getting a net::ERR_SPDY_PROTOCOL_ERROR 200 every 33 seconds or so.
I have the latest version of Chrome(v71).
What am I doing wrong?
This is the function in my Java Spring Boot Server:
@CrossOrigin
@RequestMapping(path = {"/sse"})
public SseEmitter handleSse(@RequestParam String callId) {
SseEmitter emitter = new SseEmitter(7200000L);
this.emitters.put(callId, emitter);
emitter.onCompletion(() -> this.emitters.remove(callId));
emitter.onTimeout(() -> this.emitters.remove(callId));
return emitter;
}

Turns out the issue was with the server request timing out. Our servers had a limit of 30 seconds for a response to be sent to a request. But an event source request needs to stay alive for longer.
Changing the server timeout limit fixed the issue.
