How to make the Content-Type header not fly away in axios post request?

Question

AJAX

Good afternoon!

axios
                    .post('http://api.domen/controller/action', json_obj, {
                        headers: {
                            'Authorization': 'Bearer asdasdasdadsasd=',
                            'Content-Type': null
                        }
                    })
                    .then(response => {
                    })
                    .catch(error => console.log(error));

This: Didn't help, flies away: Content-Type: null
'Content-Type': null

At the entry point to the application (main.js or index.js), set the settings for axios, for example:
In general, it's better to look at the documentation, because. perhaps this header is required for the HTTP protocol or sent automatically by the browser.
UPD: Here are different options https://github.com/axios/axios/issues/382

axios.defaults.headers.common = {};
axios.defaults.headers.common.accept = ‘application/json’;

or

transformRequest: [(data, headers) => {
    delete headers.common['Content-Type']
    return data
}]
