NoSessionException when user does not init()

[HowieG]

📥 Pull Request

📘 Description
The sessions overhaul made it such that we are expecting a session when user never calls init(). For crew this shows up as @track_agent erroring bc "No session". safe_get_session() raises an error when no session exists, but no session should exist bc user never inits. Affects more than @track_agent

🎯 Goal
only check for session when init() called (global is_initialized = True)

🔍 Additional Context
User complaining in Discord and I recreated in examples/crew/job_posting.py

🧪 Testing
TODO

Thank you for your contribution to Agentops!

[bboynton97]

this fixes it in the SDK but we still need to determine why we were being called at all if nothing agentops was in the script

[bboynton97]

as is, this breaks a lot of tests. i think this is bnot sending the first call to agentops

I refactored how state is being managed and it fixed the tests. this is now working as expected with agentops alone and with crew

[siyangqiu]

Some questions about design. We can skip if this is urgent

[HowieG]

Is this good to go @bboynton97 ?
