I am new to NodeJs, I created several APIs for my application with different methods and they all work fine, the issue is that I created a new API in the same file where I have the others but when calling it from my FE it is called twice, one is prefligth with options method and another is pending but without method... Attached screenshots..API Call

This is my API code:

router.put("/carrousel-item/update/:id", fileUpload, (req, res) => {
req.getConnection((err, conn) => {
try {
  const image = fs.readFileSync(
    path.join(__dirname, "../images/"   req.file.filename)
  );
  const title_en = req.body.title_en;
  const title_es = req.body.title_es;
  const sub_title_color_1_en = req.body.sub_title_color_1_en;
  const sub_title_color_1_es = req.body.sub_title_color_1_es;
  const sub_title_color_2_en = req.body.sub_title_color_2_en;
  const sub_title_color_2_es = req.body.sub_title_color_2_es;
  try {
    conn.query(
      `UPDATE home_team_section SET ? WHERE id = ?`,
      [
        {
          title_en: title_en,
          title_es: title_es,
          sub_title_color_1_en: sub_title_color_1_en,
          sub_title_color_1_es: sub_title_color_1_es,
          sub_title_color_2_en: sub_title_color_2_en,
          sub_title_color_2_es: sub_title_color_2_es,
          image: image,
        },
      ],
      (err, rows) => {
        res.send(rows);
      }
    );
    } catch (error) {
      console.log(error);
    }
  } catch (error) {}
  });
});

This problem is not letting me advance with the project since it does not let me execute any new API

Note: I have added the cors()

I hope you can help me
