I do an axios get(url + this.state.user) but the parameter is undefined for no reason because when i do a console log of the parameter it exists...

My code

    state = {
        user: [],
        taches : [],
        loading: false
    }

    componentDidMount = () => {
        this.setState({loading:true})
        axios.get('/get-user').then(response => {
                this.setState({user : response.data});
        }).catch(error => {
            console.log(error);
        })
        axios.get('/get-taches/' + this.state.user.ID_Users).then(response => {
            console.log(this.state.user.ID_Users);
        }).catch(error => {
            console.log(this.state.user.ID_Users);
            console.log(error);
        })
    }

The parameter of axios get-taches return undefined but when i do a console log of it in the catch error it is defined and it shows in the console... I dont know where the problem is.

Thank you for your help
