Smart API only working on Terminal. No where else?

aasiph

Creating a index.js file with code below and running it with command node index.js on terminal works perfectly. I get the jwtToken and holding details using that jwtToken.

async function fetchData() {
  
  var data = JSON.stringify({
    clientcode: "MyClientCode",
    password: "MyPassword",
    totp: "123456",
  });

  const loginResponse = await fetch("https://apiconnect.angelone.in/rest/auth/angelbroking/user/v1/loginByPassword", {
    method: "POST",
    headers: {
      Accept: "application/json",
      "Content-Type": "application/json",
      "X-ClientLocalIP": "",
      "X-ClientPublicIP": "",
      "X-MACAddress": "",
      "X-UserType": "USER",
      "X-SourceID": "WEB",
      "X-PrivateKey": "myApiKey",
    },
    body: data,
  });

  const loginResponseData = await loginResponse.json();
  
  console.log("Got Response:", loginResponseData);

  if (loginResponseData.status === true) {
    jwtToken = loginResponseData.data.jwtToken;
    const holdingResponse = await fetch("https://apiconnect.angelone.in/rest/secure/angelbroking/portfolio/v1/getHolding", {
      method: "GET",
      headers: {
        Accept: "application/json",
        "Content-Type": "application/json",
        "X-ClientLocalIP": "",
        "X-ClientPublicIP": "",
        "X-MACAddress": "",
        "X-UserType": "USER",
        "X-SourceID": "WEB",
        "X-PrivateKey": "myApiKey",
        "Authorization": `Bearer ${jwtToken}`,
      },
    });
    const holdingResponseData = await holdingResponse.json();
    console.log("Got Holding:", holdingResponse.data);
  } else {
    console.log("Login Error");
  }
}

fetchData();

But the same code does not work on any web framework backend. I tried using Express and NUXT which are based on node.js.
Infact i tried in different languages like php, c#, flutter but all fail in login endpoint giving response

{
  success: false,
  message: 'Invalid Token',
  errorCode: 'AG8001',
  data: ''
}

I am not sure what is the issue. Please any solution for this.
