I am using this library to modify an existing OPCUA test server that is connected to a device with an OPCUA client.
the connection works to a point and then it failed with this error message. note: i modified the permission_rules.py so that the check_validity always returns True.
sending service fault response: "The session id is not valid." (BadSessionIdInvalid)
Unknown message received NodeId(Identifier=841, NamespaceIndex=0, NodeIdType=<NodeIdType.FourByte: 1>) (User(role=<UserRole.Admin: 0>, name='smartgate'))
sending service fault response: "The server does not support the requested service." (BadServiceUnsupported)
sending service fault response: "The session id is not valid." (BadSessionIdInvalid)
however, this results on sending service fault response: "The session id is not valid." (BadSessionIdInvalid)
which I am guessing due to TransferSubscriptionsRequest actually need the subscription to be transferred from some session A to some session B.
I saw that in internal_session.py this function is not yet implemented
async def transfer_subscriptions(self, params: ua.TransferSubscriptionsParameters) -> List[ua.TransferResult]:
# Subscriptions aren't bound to a Session and can be transfered!
# https://reference.opcfoundation.org/Core/Part4/v104/5.13.7/
raise NotImplementedError
I have looked at the reference, however i found the description to be a bit vague.
Is there anyone familiar with this request? and what kind of implementation is actually needed to be added for the transfer_subscription function ?

I tried to mimic the work that was done on this issue https://github.com/FreeOpcUa/python-opcua/issues/594 where I always return 'ua.StatusCodes.Good'
however, this results on
