JS FetchAPI Get Request add raw body data [duplicate]

Question

I have a GET request setup in Postman with raw body data as below and it works. I can get data from the server

But my Js fetch api I'm not sure how to add request body data to it. Here is my GET request config

var requestOptions = { method: 'GET', headers: myHeaders, body: raw, redirect: 'follow' }; fetch("https://example.net:/app/v1/cmp/displacer/url", requestOptions) .then(response => response.text()) .then(result => console.log(result)) .catch(error => console.log('error', error));

But it returns error

error TypeError: Failed to execute 'fetch' on 'WorkerGlobalScope': Request with GET/HEAD method cannot have body.

The server only accept GET request for that URL. I tried to googled but no luck. Thank you for your time.

Sending a BODY (a.k.a. payload) in a GET request is unsupported by fetch because its behavior is undefined in HTTP and a lot of other systems don't support it or handle it in unexpected ways. If you need to send a BODY along, you should probably be using a different method than GET; If you need to send parameters with your GET request, you can try sending a query string.
