I change the profile photo but it doesn't change

[Avolis]

I login using cookies and try to change profile photo. Sometimes it works but sometimes not. Do you have any idea why it doesn't work sometimes?

     

community.loggedIn((err, log) =>{

            if(log == true){

 

                console.log("logged in");

                community.uploadAvatar("animage.png", null, (err, url) =>{

                          if(err){

                               throw err;

                          }              

                          else{

                               console.log("success");

                          }                 

        })

})
