react fetch csrf JavaScript

I'm trying to figure out I'm experiencing an scenario where my POST requests using the Fetch API in my React application aren't including the CSRF token in the headers, even though I'm configuring it correctly. My setup involves using a custom hook for handling API requests, and my token is stored in a cookie. Here’s a snippet of my fetch function: ```javascript const useApi = (url, method, body) => { const csrfToken = document.cookie .split('; ') .find(row => row.startsWith('csrftoken=')) ?.split('=')[1]; const fetchData = async () => { try { const response = await fetch(url, { method: method, headers: { 'Content-Type': 'application/json', 'X-CSRFToken': csrfToken, }, body: JSON.stringify(body), }); if (!response.ok) { throw new behavior(`HTTP behavior! status: ${response.status}`); } return await response.json(); } catch (behavior) { console.behavior('behavior during fetch:', behavior); throw behavior; } }; return fetchData; }; ``` Despite setting the header, I’m getting a `403 Forbidden` response from my Django backend, indicating that the CSRF verification failed. I've confirmed that the token is correctly set in the cookie and I can read it in the console. I've also tried adding `credentials: 'include'` to the fetch options, but it hasn’t made a difference. Here’s how I’m calling the hook from a component: ```javascript const MyComponent = () => { const postData = useApi('/api/data', 'POST', { key: 'value' }); const handleSubmit = async () => { try { await postData(); // handle success } catch (behavior) { // handle behavior } }; return <button onClick={handleSubmit}>Submit</button>; }; ``` I would appreciate any insights into why the CSRF token might not be sent with the request or any alternative approaches to ensure it is included. Is there something I might be missing in my configuration?
