Advanced http-cordova missing "onFail" callback function

#1

I’m using the advanced-http cordova plugin. Followed all their steps in their github repo (https://github.com/silkimen/cordova-plugin-advanced-http#post)

But when I try to run my code an error pops up:

missing mandatory "onFail" callback function

Here’s how my code looks like:

 cordova.plugin.http.post('http://127.0.0.1:5000/api/register', {
        username: this.username, 
        password: this.password,
        firstname: this.firstname,
        middlename: this.middlename,
        lastname: this.lastname,
        birthday: this.birthday,
        age: this.age,
        contact: this.contact,
        address: this.address,
        prisoner: this.prisoner
    }, response => {
        
        try {
            response.data = JSON.parse(response.data);
            // prints test
            console.log(response.data.message);
          } catch(e) {
            console.error('JSON parsing error');
          }
        }, response => {
          // prints 403
          console.log(response.status);

          //prints Permission denied
          console.log(response.error);
        });

What am I missing here? :thinking: Please help
