Expressjs API variables undefined - node.js

Question

i'm trying to create my first API using nodejs / express js for backend and React for frontend. I'm able to call the API via postman but not via localhost on frontend as the path returns "undefined" and my "mediaType" and "id" are undefined.
The frontend should call the API
BACKEND
const express = require("express");
const app = express();
const PORT = 8080;
const axios = require("axios");
app.use(express.json());
app.get("/test", (req, res) => {
// const { mediaType, id } = req.params;
const { mediaType, id } = req.body;
const options = {
methond: "GET",
url: `https://api.themoviedb.org/3/${mediaType}/${id}?api_key=${APIKEY}&language=en-US`,
// headers: {
// }
};
axios.request(options).then((response) => {
res.send(response.data);
}).catch((error) => {
console.log(error)
})
});
FRONTEND
const fetchData = async () => {
const { data } = await axios.get(
`http://localhost:8080/test`, { params: { mediaType: mediaType, id: id } }
);
setContent(data);
};
PART OF HEADER
_header: 'GET /3/undefined/undefined?api_key=XXX&language=en-US HTTP/1.1\r\n' +
'Accept: application/json, text/plain, */*\r\n' +
'User-Agent: axios/0.27.2\r\n' +
'Host: api.themoviedb.org\r\n' +
'Connection: close\r\n' +
'\r\n',

Alright, for anyone interested...
i updated the FE req
const fetchData = async () => {
const { data } = await axios.get(
`http://localhost:8080/test2?mediaType=${mediaType}&id=${id}`
);
setContent(data);
};
And changed the BE req also, to use query parameters
app.get("/test2", (req, res) => {
// const { mediaType, id } = req.params;
mediaType = req.query.mediaType;
id = req.query.id;
const options = {
methond: "GET",
url: `https://api.themoviedb.org/3/${mediaType}/${id}?api_key=${apiKey}&language=en-US`,
// headers: {
//
}
};
axios
.request(options)
.then((response) => {
res.send(response.data);
})
.catch((error) => {
console.log(error);
});
});
Also needed to update CORS (no idea how it works????) as it blocked my localhost testing
const cors = require("cors");
app.use(
cors({
origin: "http://localhost:3000",
credentials: true, //access-control-allow-credentials:true
optionSuccessStatus: 200,
})
);
Now it seems that everything works!

You accept body parameters in your API endpoint
so with axios you should use data parameter with your body data included and send it to your backend:
const fetchData = async () => {
const { data } = await axios.get(
`http://localhost:8080/test`, { data: { mediaType: mediaType, id: id } } <--- check data key here
);
setContent(data);
};
by the way, it's not a good idea to send body HTTP request with GET http verb
