load_type_definitions not working

[acuna-luis]

Hello, I am working with a S7-1200 but I can't read a structure properly. My output before and after load_type_definitions

BEFORE
node object ns=4;i=5
node object value ExtensionObject(TypeId:FourByteNodeId(ns=4;i=4), Encoding:1, 2176 bytes)
params obj {'server': <opcua.client.ua_client.UaClient object at 0x7f4fa8452f40>, 'nodeid': NumericNodeId(ns=4;i=5), 'basenodeid': None}

AFTER self.client.load_type_definitions()
node object ns=4;i=5
node object value ExtensionObject(TypeId:FourByteNodeId(ns=4;i=4), Encoding:1, 2176 bytes)
params obj {'server': <opcua.client.ua_client.UaClient object at 0x7f4fa8452f40>, 'nodeid': NumericNodeId(ns=4;i=5), 'basenodeid': None}
'_freeze': True}

And when accessing an existing atribute I got error.
ERROR
OPCUA Exception: <class 'AttributeError'>
Traceback (most recent call last):
File "/home/lacuna/dsa/internal/hw-dashboard/flow-control-operator/modules/devices.py", line 549, in update_DB
print("hola", hola.disponible)
AttributeError: 'ExtensionObject' object has no attribute 'disponible'

The code is:

                print("BEFORE")
                print("node object", self.db.obj)
                print("node object value", self.db.obj.get_value())
                print("params obj",get_object_params(self.db.obj))
                print("params val",get_object_params(self.db.obj.get_value()))
                print("AFTER")
                self.client.load_type_definitions()
                print("node object", self.db.obj)
                print("node object value", self.db.obj.get_value())
                print("params obj",get_object_params(self.db.obj))
                print("params val",get_object_params(self.db.obj.get_value()))
                var1 = self.db.obj.get_value()
                print("var1", ``var1.disponible)```

Please, your help if you have any idea. Thanks
