Answer 1

var Url = "https://----------";
    return fetch(Url, {
        method: "POST",
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({'number': '11111111-'})
    })
        .then((response) => response.text())
        .then((responseJson) => {
             const resposeJson2 = responseJson.length ? JSON.parse(responseJson) : {};
            console.log("SEND_SMS RESULT: ",responseJson2);
        })
        .done();

Your server is returning null instead of error and unfortunately response.json() cant operate on null response you can research briefly on it the keywords are "Handling null response from api"
