How to post data from js client to golang server

I want to create a simple rest api authorization service where js/html is client, golang is server and postgres is db. I had success posting body from postman and I received expected answer and data were added to db. But when I am trying to do the same from my js/html client the answer is null - {"message":"Invalid request","status":false}.

Here is my golang example code:

var CreateAccount = func(w http.ResponseWriter, r *http.Request) {
    account := &models.Account{}
    err := json.NewDecoder(r.Body).Decode(account) //decode the request body into struct and failed if any error occur
    if err != nil {
        utils.Respond(w, utils.Message(false, "Invalid request"))
        return
    }

    resp := account.Create() //Create account
    utils.Respond(w, resp)
}

Client:

'use strict'

const form = document.getElementById('form');
const url = "http://localhost:8080/api/user/login";


const myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");

form.addEventListener('submit', (e) => {
    e.preventDefault();

    const data = new FormData(form);

    let preparedData = JSON.stringify([...data].flat());
    console.log(preparedData)

    fetch(url, {
        method: "POST",
        body: data,
    })
        .then(response => response.text())
        .then(result => console.log(result))
        .catch(error => console.log('error', error));
});

    <!-- MAIN END -->
    
    <footer class="footer">

    </footer>
    <script src="script.js"></script>
</body>
</html>

Please tell me where there might be a problem on a server or client and why?

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
