Post connection works when testing but not on frontend

I am trying to get a response from a custom API end point that I made though I got

{"errors":[{"message":"The requested resource was not found."}]}

Testing on postman and this doesn't happen, wonder what is the issue. Both the frontend and backend are locally hosted. Am I missing something?

Example code of the Collection

const Sessions: CollectionConfig = {
    slug: 'sessions',
    access: {
        read: () => true,
    }
    // Random field and stuff
    endpoints: [{
        path: '/create'
        method: 'post'
        handler: async (req, res, next) => {
            res.status(200).send({ 
                message: 'Success',
            });
        }
    }]
}

Fetch request is just this (Don't mind the url, unless it is the issue, I am testing this locally first)

await fetch('http://localhost:3000/api/sessions/create', {
    method: 'POST',                
    headers: {
        "Content-Type": "application/json",
    },            
});

Switching to 'get' and it works, though that's not the main issue here. Again, if I send a post request to this endpoint through postman it works as intended.

Nevermind, took me a while to realize I need

when sending resquest. This is why you should sleep
