Hi @Ankur Bawiskar,

I am getting this error "Error: Cannot read property "variables" from null,Detail: Cannot read property "variables" from null" in flow designer while using flow designer for creating new user.

code:

var nameProvided = current.variables.employee_name;

var names = nameProvided.split(' ');

var firstName = names[0];

var lastName = names[1];

var userName = firstName.charAt(0)+lastName;

var isUnique = false;

var userNameUsed = '';

var email = '';

var gr0 = new GlideRecord('sys_user');

gr0.addQuery('username', userName);

gr0.query();

if (!gr0.next()) {

isUnique = true;

userNameUsed = userName;

email = firstName + '.' + lastName + '@XYZ.com';

}

var i=1;

while(isUnique == false)

{

var gr2 = new GlideRecord('sys_user');

gr2.addQuery('username', userName + i);

gr2.query();

if (!gr2.next()) {

isUnique = true;

userNameUsed = userName + i;

email = firstName + '.' + lastName + i+'@XYZ.com';

}

else

{

    var gr2 = new GlideRecord('sys_user');

    gr2.addQuery('username', userName + ++i);

    gr2.query();

    if (!gr2.next()) {

    isUnique = true;

    userNameUsed = userName + i;

    email = firstName + '.' + lastName + i+'@XYZ.com';   

}

}

}

Hi,

what is this action Update RITM Variable?

Is that a custom action created?

Hi,

Custom action, validating user name.

what input you are sending and what output you are getting?
