"error":{"code":-32007,"message":"The session does not exist."

[jrivd]

Hi, I am getting this error whenever I launch a:

message = {
        "id": 8,
        "jsonrpc": "2.0",
        "method": "updateSession",
        "params": {
            "cortexToken": cortex_token,
            "session": session_id,
            "status": "active"
        }
    }

There is clearly a problem with the session, becaause if I fire a "method": "querySessions", it returns empty: Received response: {"id":1,"jsonrpc":"2.0","result":[]}.

However, all the previous steps seem to be correct and the session opens just fine:

Received response: {"id":4,"jsonrpc":"2.0","result":{"appId":"***","headset":{"connectedBy":"bluetooth","dfuTypes":["dfuOta"],"dongle":"0","firmware":"a11","firmwareDisplay":"0x0a11","id":"INSIGHT2-****","isDfuMode":false,"isVirtual":false,"motionSensors":["Q0","Q1","Q2","Q3","ACCX","ACCY","ACCZ","MAGX","MAGY","MAGZ"],"sensors":["AF3","T7","Pz","T8","AF4"],"settings":{"eegRate":128,"eegRes":16,"memsRate":32,"memsRes":16,"mode":"INSIGHT"},"status":"connected","virtualHeadsetId":""},"id":"*****","license":"","owner":"*****","performanceMetrics":[{"apiName":"attention","displayedName":"Attention","name":"attention","shortDisplayedName":"At"},{"apiName":"eng","displayedName":"Engagement","name":"engagement","shortDisplayedName":"En"},{"apiName":"exc","displayedName":"Excitement","name":"excitement","shortDisplayedName":"Ex"},{"apiName":"str","displayedName":"Stress","name":"stress","shortDisplayedName":"St"},{"apiName":"rel","displayedName":"Relaxation","name":"relaxation","shortDisplayedName":"Re"},{"apiName":"int","displayedName":"Interest","name":"interest","shortDisplayedName":"In"}],"recordIds":[],"recording":false,"started":"2023-09-15T15:42:07.717+02:00","status":"opened","stopped":"","streams":[]}}

I really don't know what else to try. Thanks in advance for your support.

Can you try to createSession with active, so that you don't have to call updateSession?

Hi, thanks. I have tried to run directly:

if __name__ == "__main__":
    message = {
        "id": 4,
        "jsonrpc": "2.0",
        "method": "createSession",
        "params": {
            "cortexToken": cortex_token,        
            "headset": "INSIGHT2-A3D20705",
            "status": "active"
        }
    }

    asyncio.run(retrieve(message))

But it actually does not change much, as on the "querySessions" it still returns empty: Received response: {"id":1,"jsonrpc":"2.0","result":[]}.

@jrivd did you call querySessions right after you createSession? Please note that session is not stored anywhere after you close the session or you terminate your app, so if you call querySessions for previous sessions, it doesn't return anything.

Yes, I am indeed running this code on a jupyter notebook:

# request access

if __name__ == "__main__":
    message = {
        "id": 1,
        "jsonrpc": "2.0",
        "method": "requestAccess",
        "params": {
            "clientId": clientId,
            "clientSecret": clientSecret
        }
    }
    asyncio.run(retrieve(message))
    
# query headsets

if __name__ == "__main__":
    message = {
        "id": 1,
        "jsonrpc": "2.0",
        "method": "queryHeadsets"
        }

    asyncio.run(retrieve(message))    
    
    
# connect headset

if __name__ == "__main__":
    message = {
        "id": 2,
        "jsonrpc": "2.0",
        "method": "controlDevice",
        "params": {
            "command": "connect",
            "headset": "INSIGHT2-A3D20705"
        }
    }

    asyncio.run(retrieve(message))   

# authorise

if __name__ == "__main__":
    message = {
        "id": 3,
        "jsonrpc": "2.0",
        "method": "authorize",
        "params": {
            "clientId": clientId,
            "clientSecret": clientSecret,
            "debit": 10
        }
    }
    
    asyncio.run(retrieve(message))

# create session

if __name__ == "__main__":
    message = {
        "id": 4,
        "jsonrpc": "2.0",
        "method": "createSession",
        "params": {
            "cortexToken": cortex_token,        
            "headset": "INSIGHT2-A3D20705",
            "status": "active"
        }
    }

    asyncio.run(retrieve(message))

# query sessions

if __name__ == "__main__":
    message = {
        
        "id": 1,
        "jsonrpc": "2.0",
        "method": "querySessions",
        "params": {
            "cortexToken": cortex_token        

        }

    }

    asyncio.run(retrieve(message))

Many thanks in advance for your support on this issue.
