hello, I've been trying to post to my facebook page when i add a product into the website using express... im new to coding with the facebook api so i dont know why does this cause an error ... thank you very much !

app.post("/products/r", async (req, res) => { // saves the new product from the admin console 
  const newProduct = new Product(req.body);
  await newProduct.save();

  const productName = newProduct.name;
  
  const postMessage = `שלום חברים נוסף לאתר מוצר חדש בשם : `;
  
  const apiEndpoint = `https://graph.facebook.com/${pageId}/feed`;
  try {
    const response = await axios.post(apiEndpoint, {
      message: postMessage,
      access_token: accessToken,
    });
  
    if (response.status === 200) {
      const json = { message: 'Posted to Facebook successfully' };
      res.status(200).json(json);
    } else {
      const json = { error: response.data };
      res.status(response.status).json(json);
    }
  } catch (error) {
    console.error('Error posting to Facebook:', error.response.data);
    const json = { error: 'An error occurred while posting to Facebook' };
    res.status(500).json(json);
  }

});

you should check the page id in your facebook page and try and send a post request... also theres a page token and a user token which are totally diffrent.
