Passing payload in GET request not working

Question

I am using someone else's API and they unfortunately set up a GET request to send data to query a string and get back a list of objects with some sentences that match the string.

Now I have to use it for the part I am working on in the project.

On Postman when I make a GET request with the following format as a JSON object:

I get back the following data in the BODY which shows that it works:

        }
    ]
}

I referenced this question and found a way to send the string as a query using a GET request.

  const getDescription = async (string) => {
    const response = await fetch("/rank/" + string, {
      method: "GET",
      headers: {
        Accept: "application/json",
        "Content-Type": "application/json",
      },
    });
    console.log(response);
  };

  useEffect(() => {
    getDescription("hello");
  }, []);

But I am getting a 404 Error:

Response
​
body: ReadableStream { locked: false }
​
bodyUsed: false
​
headers: Headers {  }
​
ok: false
​
redirected: false
​
status: 404
​
statusText: "NOT FOUND"
​
type: "basic"
​
url: "http://localhost:3000/rank/hello"

How would I get this to work if it even is possible?

Edit: I resorted to making the other person create a POST request instead.
