Return promise in enable rule

I have written code using fetch to return a Promise to Dynamics in an Enable Rule, but I am not receiving the correct data in return to Dynamics.

If I test with a simple function like this in Dynamics it works:

function enableButton() { 
    return new Promise(function (resolve, reject) {
                var test = true; 
                resolve(test); 
            }, 
            function (error) { 
                reject(error.message); 
                console.log(error.message); 
            } 
        ); 
    }

If I do it like this it does not return the promise correct:


function enableButton() { 
    fetch(accesstokenUrl, {
        method: 'POST',
        body: 
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded'
        }
    })
        .then(function (response) {
            return response.json();
        })
        .then(function (resJson) {
            return fetch(url, {
                method: 'POST',
                headers: {
                    'Authorization': 'Bearer '   resJson.access_token,
                    'Content-Type': 'application/json'
                },
                body: JSON.stringify(
                    {
                        "queryparams": true
                    })
            });
        })
        .then(function (res) {
            return res.json();
        })
        .then(function (data) {
         const hasDebtCase = getDebtCase(data);
              if (hasDebtCase) {
                return Promise.resolve(hasDebtCase);
            } else {
                return Promise.reject(data);
            }  
        })
        .catch((error) => {
            console.error('Error:', error);
        })
};

What is the problem with this?
