C++ binary search tree using recursion, return node problem

Question

I am trying to create a function that receives a node and a value to enter into the tree. I am passing values as (Node* node, int value). But when I return that node the error message appears as "No suitable constructor exists to convert from "Node" to "Node". I have seen a few questions much similar to my problem but I was unable to understand the answers provided. I am new to the tree Data structure concept, So please try to explain it simply.

class Node {
    public:
        int data;
        Node* left;
        Node* right;
        Node(int value)
        {
            data = value;
            left = right = nullptr;
        }
    };
    Node* root = nullptr;
    
    Node insert(Node *node, int value)
    {
        if (node == nullptr)
        {
            node = new Node(value);
            return node;
       }
    
    }

Answer 1

You are trying to return a pointer to Node but the signature of the method says you want to return a Node value. Change the return signature to a pointer of Node

Node* insert(Node *node, int value)
{
    if (node == nullptr)
    {
        node = new Node(value);
        return node;
    }
    // also problem here if node is a nullptr, how to handle this
    // you could throw exception or return nullptr
    return nullptr;

}
