Excuse me, I want to write part value to an array node, for example, after write 1,1,1 to a int32_t[10] node, the node value changed to [1,1,1,0,0,0,0,0,0,0]

I change the ClientExample code as bleow , the question is i can write the first element for the array node, when count > 1, receive error "[Error: Read] The

operation timed out Status Code:0x800a000". Who can tell me what's the problem? Thank you!!
.
//<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< code start <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Status_t ClientConsole_t::WriteNumber(IntrusivePtr_t<IClientSession_t> &session,
IntrusivePtr_t<NodeId_t> &write_node,
uint32_t dataTypeId,
uint16_t &write_value)
{
IntrusivePtr_t<WriteRequest_t> writeRequest = new SafeRefCount_t<WriteRequest_t>();
IntrusivePtr_t<WriteResponse_t> writeResponse;

status = writeRequest->NodesToWrite().Initialise(1);

ArrayUA_t<WriteValue_t> &nodesToWrite = writeRequest->NodesToWrite();

nodesToWrite[0] = new SafeRefCount_t<WriteValue_t>();
nodesToWrite[0]->AttributeId() = AttributeId_t::ATTRIBUTE_ID_VALUE;
nodesToWrite[0]->NodeId() = write_node;
nodesToWrite[0]->DataValue() = new SafeRefCount_t<DataValue_t>();

IntrusivePtr_t<ArrayUA_t<Int32_t>> valueArray = new SafeRefCount_t<ArrayUA_t<Int32_t>>();
//***** count =1 can write the first elment of the array node, when count > 1 receive error and can't write any element..******
int count = 2;
valueArray->Initialise(count);
for (int i = 0; i < count; i++)
{
IntrusivePtr_t<Int32_t> num = new SafeRefCount_t<Int32_t>();
//for test every element is the same value
*num = (int32_t)write_value;
(*valueArray)[i++] = num;
}

nodesToWrite[0]->DataValue()->Value() = valueArray;

status = session->Write(writeRequest, writeResponse);

...

}
