Reading a quite complex extension object

[pridi]

Hello everyone, I'm facing an issue when I try to read a structure like this (IcsEvoShifts in the picture):

When I try to get value before executing the load_type_definitions(), I correctly see in the body the bytes stream:

but after executing the load_type_definitions() and executing again the get_value(), I receive a Not enough data left in buffer:

raise NotEnoughData("Not enough data left in buffer, request for {0}, we have {1}".format(size, self))
opcua.common.utils.NotEnoughData: Not enough data left in buffer, request for 296960, we have Buffer(size:700,...

This is the very simple snipped code I have:

client.connect()

struct=client.get_node("s=IcsEvoShifts")
root = client.get_root_node()
objects = client.get_objects_node()
children = root.get_children()
child_of_children=children[0].get_children()
print("child_of_children  :",child_of_children)
c_child_of_children=child_of_children[3].get_children()
Day0 = c_child_of_children[5].get_children()
Shift0 = Day0[5].get_children()
print("c_child_of_children  :", c_child_of_children)
structs = client.get_node(c_child_of_children[5])
before = struct.get_value()

client.load_type_definitions()

after = struct.get_value()

Could you please explain me what could the issue?

Thanks
