Hi...i'am using jquery -v3.5.1 and jquery.validate -v1.9.2

My code is
var settings = $('form').validate().settings;
settings.rules['UserPrincipalName'].required = true;

it gives error
VM155:294 Uncaught TypeError: Cannot set property 'required' of undefined

When i was on older version jquey -v2.1.4 then it was working fine but now not working with jquey- v3.5.1

Please give some solution on it.
I go through lots of link but not getting related to this.
Please let me know how can i fix this issue.
