how to access meteor ReactiveVar variable in meteor call in onRendered

I want to access ReactiveVar variable in onRendered getting error Exception in delivering result of invoking 'getUsersData': TypeError: Cannot read property 'userData' of null

    Template.editAdmin.onCreated(function() {
     this.userData = new ReactiveVar([]);
   });

   Template.editAdmin.onRendered(function() {
     Meteor.call("getUsersData", this.data, function(err, result) {
        Template.instance().editAdminId.set(result);
      });
   });

It doesn't look like your code sample lines up with your error message. You mentioned the error is:

TypeError: Cannot read property 'userData' of null

but from looking at your code sample, I can see the error will really be:

TypeError: Cannot read property 'editAdminId' of null

I'll assume you want it working with userData, so I'll adjust your code accordingly. Basically you want to make sure you're leveraging javascript closure properly when using Template.instance() in your Method callback. For example:

Template.editAdmin.onCreated(function () {
  this.userData = new ReactiveVar([]);
});

Template.editAdmin.onRendered(function () {
  const instance = Template.instance();
  Meteor.call("getUsersData", this.data, function (err, result) {
    instance.userData.set(result);
  });
});
