[iffikhan30]

// Handle GET request
app.get("/apps/proxy", async (_req, res) => {
  console.log("GET API");
  try {
    console.log("trying...");
    res.status(200).send({ message: "Got it" });
  } catch (error) {
    res.status(500).send(error.message);
  }
});

When i hit the URL without shopify.validateAuthenticatedSession() it work fine, but when I call on my component

const textProxy = (d) => {
  return new Promise((resolve, reject) => {
    fetch("SHOP-URL/apps/proxy", {
      method: 'POST',
      redirect: 'manual',
      headers: {
        'Content-Type': 'application/json',
        'Access-Control-Allow-Origin': '*'
      },
      body: JSON.stringify(d)
    })
    .then(response => {
      console.log(response, 'response');
      return response; // Assuming the response is in JSON format
    })
    .then(data => {
      resolve(data);
    })
    .catch(error => {
      reject(error);
      console.log("test", error);
    });
  });
};
