Arrow function, this and promise

[darakt]

Hi, I change recently to Axios and I can't figure why the this isn't "working" properly inside the promise.
`let all = {
method: 'POST',
url: 'https://XXXXXX',
data: data,
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json',
}
};

    axios(all)
        .then((response) => {
            this.setState({
                ...this.state,
                spin: false,
            });
            self.props.router.push('panel');
        })
        .catch((error) => {
            this.setState({
                spin: false,
                errorLogin: 'Username or password wrong',
            });
        });`

In the end my this.setState is not a function which the use of an arrow function should avoid...

From the code you share I can't really help, as I don't see anything wrong. I'm closing as this isn't an issue in Axios anyway.
