How to create incident and assigned that incident to user mention in mail body

[RushiM]

Hello Community,

I want a functionality that create an incident on received an email, based on that mail incident should create and prepopulate following fields, 

subject -> short description

Mail body -> description

category -> Security (not from mail)

subcategory -> Quarantine (not from mail)
Assigned to -> Email of user mention in mail after 'user:' .  ex.user:abc.xyz@example.com
so the incident assigned to Abc Xyz user.

As now I am scripting for incident is generating but Assigned to, category, subcategory is not populate.

Even the log is not displays for userName or email.

I will very greateful on our help,

Thanks in advance.

(function runAction( /*GlideRecord*/ current, /*GlideRecord*/ event, /*EmailWrapper*/ email, /*ScopedEmailLogger*/ logger, /*EmailClassifier*/ classifier) {

        var userEmail = email.body_text.user;
        gs.log("Email is " + userEmail);

        var useremail = email.body_text.user.toString();
        gs.log("email:" + useremail);
        emailParsed = emailParsed.split(' ');
        gs.info('SN Community test [email]: ' + emailParsed);
        var grUser = new GlideRecord('sys_user');
        grUser.addQuery('email', useremail);
        grUser.addQuery('email', emailParsed[0]);
        grUser._query();

        if (grUser._next()) {
            gs.info('SN Community test [IF]: ok');
            var assigned_to = grUser.getValue('caller');
            gs.log(useremail);
            var grChange = new GlideRecord('incident');
            grChange.newRecord();
            grChange.setValue('assigned_to', grUser.getUniqueValue());
            grChange.insert();
        }

})(current, event, email, logger, classifier);

Can you share the incoming email as well? If the log doesn't give you that email address, it's just not recognized.

I am also missing some background in the logic of your script: you are creating a variable 'assigned_to' from the caller (which isn't a field on the email form) and you don't do anything with it? You are defining userEmail twice?
