Code I wrote for talking with server

ajax.ts

import axios from 'axios';

	authState?: string;
	tokenType?: string;
	fullUrl?: string;
}

interface AjaxResponse {
	status: string;
	data?: any;
	error?: string;
}

async function ajax(params: AjaxRequest, method): Promise<AjaxResponse> {
	const {
		queryParams,
		url,
		body,
		auth,
		authState,
		tokenType,
		fullUrl,

		}
	} catch (error) {
		// Do refreshing
		console.log(error);
		// throw new Error('AUTHFAIL');
	}

	const headers = {
		'content-type': 'application/json',
	};

		return { status: 'failed' };
	}
	if (token && auth) {
		headers['Authorization'] = `Bearer ${token}`;
	}

	const config = {
