How to return data from Backend to Frontend

Hi,

I’m trying to return few data from backend to frontend once the registration is complete. While testing I can see that the user gets registered successfully but for some reason, the data I return from the backend method to the frontend comes with “undefined”.

Below is my Backend Code

export function doRegistration(email, password, firstName, lastName) {
    wixUsersBackend.register(email, password, {
 "contactInfo": {
 "firstName": firstName,
 "lastName": lastName
        }
    }).then((result) => {
 if (result.status === "Pending") {
            wixUsersBackend.approveByToken(result.approvalToken)
                .then((token) => {
 return {
                        token,
 "approved": true,
 "userId": result.user.id,
 "isEmailExist": false
                    }
                }).catch((err) => {
 return {
 "approved": false,
 "isEmailExist": false,
 "errorCode": err.errorCode,
 "errorMessage": err.errorDescription
                    }
                });
        }
    }).catch((err) => {
 return {
 "approved": false,
 "isEmailExist": true
        }
    });
}

I tried reading the return value from frontend in both the ways as follow:

doRegistration($w('#txtLoginEmail').value, $w('#txtPassword').value, $w('#txtFirstName').value, $w('#txtLastName').value).then(result => {
                if (result.approved) { //.approved is undefined
}
});

Also,

let result = doRegistration($w('#txtLoginEmail').value, $w('#txtPassword').value, $w('#txtFirstName').value, $w('#txtLastName').value);
if (result.approved) {  //.approved is undefined
}

Any help will be greatly appreciated!

well, I didn’t dive into the code’s logic but I had noticed some problems while reviewing it
you should add the return and await keywords as I did:

export function doRegistration(email, password, firstName, lastName) {
 return wixUsersBackend.register(email, password, {
 "contactInfo": {
 "firstName": firstName,
 "lastName": lastName
        }
    }).then((result) => {
 if (result.status === "Pending") {
            wixUsersBackend.approveByToken(result.approvalToken)
                .then((token) => {
 return {
                        token,
 "approved": true,
 "userId": result.user.id,
 "isEmailExist": false
                    }
                }).catch((err) => {
 return {
 "approved": false,
 "isEmailExist": false,
 "errorCode": err.errorCode,
 "errorMessage": err.errorDescription
                    }
                });
        }
    }).catch((err) => {
 return {
 "approved": false,
 "isEmailExist": true
        }
    });
}

let result = await doRegistration($w('#txtLoginEmail').value, $w('#txtPassword').value, $w('#txtFirstName').value, $w('#txtLastName').value);
if (result.approved) { //.approved is undefined
}
