AEM 6.5 cloud - Reset password

Avatar

Level 1

Hi Team,

I have a requirement where user want to have two options:

1. reset password by accepting old password

2. Forgot password option by triggering an email to users inbox and then they can change the password through the link.

 

For the first requirement, I've an ajax call as below:

 

    var origin   = window.location.origin;
    var URL = origin + "/content/dam.resetpw.html";
    
    var currentURL = window.location.href;
    var redirectURL = (currentURL.substring(0, currentURL.lastIndexOf("/") + 1)).concat("sign-on.html");

    $('#asc-reset-password-form-id').submit(function(e){
        $.ajax({
            type:'POST',
            data: $('#asc-reset-password-form-id').serialize(),
            url: URL,
			error:function(){
                alert("Failed to reset the password");
                window.location = currentURL;                
            },
            success:function(){
                alert("Password has been reset successfully");
                window.location = redirectURL;

            }
        })
    });    

 

   And the java code as:

Unfortunately, I'm getting 500 error on the ajax call and 422 error un-processable entity next:

Can someone help me with this?

Hi @lakshmi_anil 

 

Can you please check the error logs to debug the 500 server error?
You can get the info about failure in logs easily and look out for servlet specific logs in error log.
