[sudhakar3697]

Code:

<script> var x="abc"; const query = { platform } fetch('http://localhost:4000/apiv1', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ query }) }) .then(r => r.json()) .then(data => {console.log('Response:', data);document.write(data.data.platform)}); </script>

Console Error:

If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
