session auto-closes after 35m of idle time #212
Description
This was unexpected & not mentioned in the docs. The downstream effects of this is that any reference to a sessionId or a CopilotSession must always attempt to manually resume(). This is more likely to occur after #76 since long-running sessions are now better enabled.
Reproduction
- create a session / send message
- wait 35m of idle time (2094s)
- attempt to send new message into same session
Error
error: Request session.send failed with message: Session not found: b23dfbfc-32f5-4eb3-a90c-1b476a180a75
