eBay get access token with Axios don't work

When I execute the following code I get the following error message: grant type in request is not supported by the authorization server
What I am doing wrong?

	const axios = require("axios");
	axios.request({
	url: "/identity/v1/oauth2/token",
	method: "POST",
	baseURL: "https://api.sandbox.ebay.com/",
	auth: {
	username: "", // eBay client id
	password: "" // eBay client secret
	},
	headers: { 'content-type': 'application/x-www-form-urlencoded' },
	data: {
	"grant_type": "client_credentials",
	"scope": "https://api.ebay.com/oauth/api_scope"
	}
	}).then(res => {
	console.log(res);
	}).catch(error => {
	console.log(error)
	})

If I remember correctly content type is Content-Type: application/json
and not x-www-form-urlencoded.
