[Community Alums]

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 Ankur,

2. Variable name employee_name.

Hi,

what type of variable is employee_name?

Did you print the value in logs

var nameProvided = fd_data.trigger.request_item.variables.employee_name;

gs.info('nameProvided' + nameProvided);

var names = nameProvided.toString().split(' ');

Regards

Hi,

the variable name is incorrect or the variable doesn't exist for that catalog item

Did you check that

please share the flow screenshot and the step where this script is written
