Make a request to ipfs-cluster API for adding new content

Help Coding

Hello community,
My goal is to add content to IPFS using JS
Here is my code

const axios = require('axios');

const pinJsonToIPFS = async function () {

    const buffer = Buffer.from('What a wonderful day');
    try {
        const result = await axios.post(
            `domain/cluster/add`,
            buffer
            , {
                headers: {
                    'Content-Type': `multipart/form-data; boundary=${undefined}`,
                }
            });


        console.log(result)
        return result.data;
    } catch (err) {
        console.log(err);
    }
}


const getJsonFromIPFS = async function (hash) {
    let result = await axios.get(`http://domain/ipfs/${hash}`);
    return result.data;
};

(async () => {
    const hash = await pinJsonToIPFS();
    // console.log(hash);

})()

The response data is always empty. How I could process adding content?
