Regular null reference exception on SSE heartbeat

ServiceStack Server Events
1

Hi,

I’m using SSE with the js client, and I am regularly getting SSE heart-beat calls fail with a null reference exception. This causes the client to rejoin. Any ideas why this may be happening?

Do you have v4.0.44 installed? If so upgrade to v4.0.46.
